The Best Onion Burgers in Oklahoma City and El Reno | Eater

"A famous diner known for its thin, smash-style onion burgers loaded with onions that range from grilled to slightly burnt; burgers are typically dressed with mustard and pickles (unless requested otherwise) and come with crispy hand-cut fries, the assertive char on the patty balancing the sweet, buttery onions and tangy mustard." - Amy McCarthy

The 29 Best Diners in America | Eater

"Located just off the old Route 66 in El Reno, this red-awning diner is a showcase for the Oklahoma onion-burger tradition—thin-shaved onions smashed into the beef on the griddle—and is best enjoyed by ordering the cheeseburger with fried onions and a side of the crispy, double-fried fries. Friendly, classic diner service and a no-nonsense menu make it a must for visitors seeking regional burger history." - Eater Staff

The Best Onion Burgers in Oklahoma City and El Reno - Eater

"Sid’s Diner is arguably the most famous of the Oklahoma onion burger slingers in El Reno, thanks in part to appearances on shows like Man Vs. Food. As its name might indicate, Sid’s serves a full diner menu, complete with omelets and chicken fried steak for breakfast, but the real draw is the onion burger." - Amy McCarthy

The Original Oklahoma smash burger, and best hands down. Adam was amazing, attentive to customers and to me he's the best! His grilling was on point with making burgers. I sat right behind the grill which to me is the best seat in the house because you've got birds eye view of the deliciousness going down. Taste was amazing and this place is legend. I live an hour and a half away and will definitely make that drive for another burger. Environment there is very welcoming and make you feel like you're at home. If you've never been here you need to go!

Sid's Diner - El Reno, Oklahoma: A Route 66 Icon and Home of the Original Onion Burger. Sid's Diner in El Reno truly embodies the classic American diner experience. As the proud home of the original Oklahoma onion burger, this small, bustling spot lives up to its reputation. We visited during the lunch rush, and while the limited seating meant a bit of a wait, it was well worth it. The hospitality here is as incredible as the food. The staff were super friendly, and the owner (a third-generation family member!) took the time to greet us personally and chat about the restaurant's rich history and its deep connections to Route 66. It's clear the passion for this place runs deep. And the food? Simply amazing. We ordered the signature original onion burger—a must-have—and a small order of fries, which, be warned, easily feeds two people! To top it all off, we shared an incredible banana shake. If you are traveling the Route 66 tour or just passing through El Reno, you absolutely have to stop here. From now on, when someone says the word "diner," Sid's is the perfect representation of good ol' Americana that you will picture in your head. Highly recommended!

I'd heard of Sids for years, but never had the opportunity to eat there. Finally was nearby and stopped in today. Burger was cooked perfectly for a fried onion burger. They are by nature messy and kinda hard to manage while eating it. Lots of onions and good hot bun. Atmosphere was typical of a diner, with limited seating and close to the action on the grill Adam was cooking and took the time to greet me and checked on me twice while I was dining. Small order of fries were more than enough for one person. Fries are fresh cut and sort of skinny, so they cook down to rather hard and crunchy type. I prefer the ones a bit thicker that preserves the flavor more, but judging from the crowd, these are popular. Most appeared to be local folks, so that's a great endorsement for the place. The burger reminded me of a Nics burger and that's about as good of a compliment as you can give a burger.. If you like onion burger, this is a must try..

This is an extremely small main building with limited seating. There is an extra building with more seating and it was cool during a hot summer day. They have a screen for placing orders but you have to go get your order from the main building yourself. No service in the extra building but not sure how it happens in the main building. The food was what you would expect when getting an onion burger. The onion rings were good and the fries were plenty to share.

I loved Sid's. Today was my first time eating there. It was a Wednesday, right at the lunch rush, but the very nice and friendly staff sat us within a few minutes when a couple spaces opened up. We sat at the counter and got to watch Marty the owner work his magic on the grill. We (my father and I) both ordered the single onion burger with cheese. We shared the half order of fries and onion rings. WOW, I have heard about these burgers for awhile now and they do not disappoint. I had sky high expectations and my burger met those. I highly recommend Sid's. I wish I had more room after for a shake but I just couldn't fit another thing in my stomach. 5 stars all around, great food, friendly and happy staff, and even though it is snug in there it feels like an old diner and I love that. There is another building separate from the main one you can eat at also but for our first time we wanted the experience. I am glad we did. I snapped one photo of Marty at the grill performing his magic and I'll add it here. Absolutely loved Sid's and I will be back!

We tried all 3 burger places famous for the onion burger in El Reno and Sid’s was by far our favorite. Adam (grandson) was working the grill like a real pro

Took my dad to Sid’s Diner for his birthday and we had a great time! They're known for their fried onion burgers, and they definitely lived up to the hype, everything we ordered was delicious. The atmosphere is classic and fun, though there is limited indoor seating, so be prepared for a bit of a wait during busy times. The staff was fantastic, and the owner even took a few minutes to chat with us on our way out. He was genuinely interested in why we were visiting, which made the whole experience feel even more special. Totally worth the 30-minute drive from the city, highly recommend giving it a try!

FAMILY'S "GO TO" for THEE OKLAHOMA ONION BURGER!!! I mentioned to our family from Mustang, OK if they knew a good place to hit, to wow us with the famous Onion Burger of Oklahoma. I mentioned a few places, however, all my brother in law had to say was, "I gatchu Dave." Spoken confidently with a wink and a smile... well, ain't gonna argue with that lol. So, off we went to El Reno, OK. Not to Oklahoma City mind you, cuz nobody there knows how to do it right in the big city! Nope! El Reno, sight of the Oklahoma Land Run of 1889, is also the spot for THEE best Oklahoma Onion Burger. There's a few grills to choose from in this town, but we planted our butts at Sid's Diner! Street parking is plentiful however the diner itself is TINY and the place is packed already at 10:30am Saturday morning. That whiff of grilled onions when you open that diner door though... INTOXICATING! Gets the rumbly tummy activated! Luckily, there is an annex with big tables, air conditioning and an order screen, which made it very convenient for our party of 8 to sit together. Okay... let's EAT! KING DOUBLE: Now THIS was truly A BIG BOY!!! A whole pound of meat with caramelized onions, undistracted by cheese, lettuce or tomatoes (which you can add, if you so choose). Just a little drizzle of mustard and ketchup. I tell you what... this was a handful, a mouthful, and an absolute pleasure to devour! This grease bomb was so flavorful with the smashed patty charred to perfection and grilled onions galore spilling over. I loved every bite of that monstrosity and I'd do it AGAIN in a heartbeat! CONEY DOG: Compared to the King Double, this was pretty timid. Definitely for smaller appetites. Just a regular sized hot dog waiting for you underneath the chili. Not chintzy with chili though which was very tasty. I did like the relish drizzle on top, it added a nice sweetness to it. FRITO CHILI PIE: I ENJOYED this with my King Double! Comes as Chili smothering a heap of crunchy Fritos and then you add the shredded cheese and diced onions to your liking. Me? I dumped it all in and in hindsight shoulda asked for more cheese, cuz I love me some cheese pull! The crunchy texture of the Fritos complimented the tastiness of the King quite well! Yummers :) TATER TOTS: Perfectly prepared tots! Crunchy outside, yet perfectly flaky within. However when compared to the size of the fries order, this was not Oklahoma Big. Did it spill out before it made it in to the bag??? Guess we'll have to come back to compare lol FRENCH FRIES: One order... Huge! Not crispy like McDonald's but that's okay with me. This had more flavor and can easily be shared between 2 people. It still tasted good as it cooled down too. PEANUT BUTTER SHAKE: I asked for extra peanut butter and I sure got it. It was a flavor explosion with every mouthful! And it was thick enough that the straws provided would collapse if you sucked too hard. The cups for the shake were tall so definitely an ample serving to enjoy the whole meal! VERY EASY RECOMMENDATION! Nom Nom Level is HIGH! We will absolutely ask for a return visit to Sid's when we come back to Oklahoma! This stuff was... GUUUUUD!!!

Sid's is the definition of a nostalgia meal. They have an old fashion greasy diner style burger which I love, but you have to have these types of meals in moderation... or at least you should! Everything came out piping hot and the portions were generous (except for the onion rings, they should include more in an order). You can easily why Sid's is a local staple in the El Reno community.

In our continuing quest to find the best breakfast place on our x-country trip, Sid's just might be "the one". Reminiscent of past trips w Unabelly. Sid's is on the smallish side, but packs a big punch. Adam is the short order cook/owner. His grandfather was Sid. My best friend, Orange Slice, and I both ordered Sid's special. Two eggs, hash browns. Choice of meat (we both ordered ham), and toast or pancake. Angelica, our server, was efficient effective, affable. Large portions, the ham tasted sugar-cured, OS's pancake was gone in three forkfuls. Coffer was $1,50 so they lost money on OS. Decor really cool. Very old pics of vets on the wall. Nice music playing. If Yelp allowed for more than 5 stars, Sid's would qualify.

Hubby & I couldn't decide what to get for dinner. We decided to try out Sid's dinner. I had the chili/fritos, oh so good with onions /shredded cheddar cheese. Hubby had chili which also came with onions/shredded cheddar cheese. We split a small salad which went real well with the chili! We split a cheese burger. Oh their hamburger is really fantastic! Prices are reasonable for a really great meal! The service was over the top, the place is clean & fun decor! Definitely worth a stop by!

Unique hamburger place. Small small dining area. Counter stools best to sit at unless you have a child. Always enjoy watching the cooks. Seemed to have different cooks since last time there. Main cook was a older lady. Hamburger not quite as good, not sure why. I couldn't help watching the French fry guy. He was a young guy working super hard. He never skipped a beat. He also was very polite! The teams seems to work well together here. They do their job well but wish they seemed happier. I need happy some days and today was one of them. You can even grab your meal and eat outside or in the enclosed table area on the side. We enjoy eating in car across street by the Route 66 sign.

What a fantastic place to grab an iconic Onion Burger. I can't believe that I have lived in Oklahoma for 25 years and I am just now finally getting to taste the Original Oklahoma Onion Burger!!! All I can say is don't wait this is a must try place to eat. One thing I did find out is that you can actually make a reservation!! I would definitely do that! Instead as you enter the restaurant you will notice the seating is limited on the inside. There is a covered seating area/pavilion which you can also place your order from! We are provided with a pager to let us know we're next in line. Our wait was probably 5 minutes so not long. While waiting we had an opportunity to review the menu. Our server was Abby and she was great and very easy to talk too! It was easy for me, I chose the 1/2 lb onion burger with everything on it. Onion rings as the side were fantastic. Thick & crispy!! I decided I wanted to try their shakes so I asked if they had a Banana & Cherry which I've never had. A great combo!! My wife chose the Steak & Shake along with fries. She got the chocolate shake - another good selection! One note to mention if you like your fries crispy do not order them crispy. Get them cooked like the normally come and they will be perfect! Overall highly recommend to put this in your must places to try!

As a newbie to Onion Burgers I was overwhelmed with the amount of onions on the burger. Nonetheless, the burger was prepared very well with grilled bun. I'll order a traditional burger next time.

It's a small place but the food is big! Big portions, huge flavor. Ordered the onion rings and the regular double with the fried onions in the burger patty. Service was quick and efficient. There's plenty of parking on the street. If they're packed, remember I said it's a small place, there's an adjacent room for overflow. Oh, and it's on historic Route 66. Memorable.

Our Thursday after game dinner was amazing. Stopped by Sid's diner in El Reno for some burgers and onion rings. The place was packed but we managed to find 2 seats at the bar. The cook, Marty was on it with about 30 burgers on the grill at once He was slapping those sucker's up in record time. You could here the sizzle of the beef and inuons and the smell wafting in the air. It was a sight to behold. The onion rings are absolutely amazing too. A big basket of crunchy hot goodness. And when those burgers were finally placed in front of us,piping hot--- we just dove in. It was quite the delicious treat. Thestaff is attentive, friendly and fast. The food is top notch for a little diner and worth the drive no matter where you are driving from in Oklahoma and beyond. I give it a ten=ten..

Sid's- if you want a truly unique experience- this dive is LEGENDARY!! I've been trying to duplicate the original onion burger w little success. If you're driving on Interstate 40 - take the time to get off the highway and skip the roadside fast food and chains. I guarantee you it's legit!

Starting off this review with facts that we did try Robert's Diner last year and would have tried Sid's the next day but they were closed for some reason. Here we are today and we were able to make lunch at Sid's!! Great atmosphere and love all of the old pictures on the walls and tables. Service was fast and with such friendliness. We had options to sit outside under the enclosed patio seating area or sit inside which is a tight fit. We found a table inside and sat down fast. They take your order table side. Outside there is an electronic pad on each table to take online orders. It works efficiently. I ordered the classic regular original burger (double patty because I can) it was piping hot & fresh upon arrival. You can order with lettuce & tomato or without, I had it with. Grilled onions were perfect and I got someone's left over mushrooms from the grill and I'm not mad about it. Next time I will order with grilled mushrooms too. My burger did not have enough salt for my taste, my husband said his was too salty which might mean accidentally over salting on his patty and not mine . Fries are ordered to share for 2 or 3 people they are the skinny fries and were most delicious. Overall it was a good experience and I'm happy we stopped to try a Sid's burger. Give Sid's a try and tell me your honest opinion.

The food was amazing and had AWESOME prices for what we got. We went twice in a day - we went for breakfast and I got the Biscuits and gravy they were outstanding! And I got a side biscuit and they came toasted and buttered - so good! My fiancé had the all meat omolette and the side of home made salsa - amazing! Went back to try the fried onion burger for lunch - it was a 10/10!! The fries were yummy too! And not to mention the service and staff were awesome! We will be back anytime we're in the area

Sid's Diner is an Icon, I had the privilege of having the amazing onion burger while talking to Sid, the service was awesome as we watched our burgers cook in a iconic diner. Sid waited till we finished our burgers to sit and talk for 20 minutes he made us feel at home in his diner. Sid thank you for your service to the United States of America. You won't go wrong with Sid's awesom little diner with great charm

Food was excellent! We had 2 steak sandwiches and an order of onion rings! Everything was delicious, the sandwiches were so big we should have split one!

The OG Oklahoma Onion Burger done right! Hands down one of the best burgers I've had in my 59 years on this Earth! Warm bun, perfectly seasoned beef and all the veggies! It is a small shop. Not a lot of indoor seating. But on nice days there is an outdoor patio. And they do stay busy! When near OKC, there are two places to go for the best burgers. Sid's in El Reno. And Nick's in OKC. Best burgers in Oklahoma.

The food here is amazing! My burger was seasoned and I loved the pickles that came with them. I didn't know it was an extra charge for veggies (it's called deluxe) I definitely didn't need them. The fries were really good too! I also got a banana shake and it was amazing!! Anyway the service was good. The food came out fast and our waiter was constantly checking on us. Great family friendly place. Small on the inside about 4 tables and countertop with about 8 seats. Anytime I'm out this way I'll def stop by!

This is an American burger institution, so we had to try it on our way down to OKC (a little out of the way, but not by much). It was pretty empty when we arrived, but the place has an overall cozy vibe and very friendly workers. We ordered the famous fried onion (depression) burger, a cheeseburger for our daughter, a large basket of fries, and a side salad. I think we're perhaps the first people to order a salad there in 50 years because here's what came out: shredded iceberg lettuce (like you would put on a burger), some diced tomatoes, and a ton of shredded cheddar cheese (like you would put on a coney dog). So, yeah, joke's on us! The fries were thin and crispy, but there was zero salt on them and then you kind of had to eat them with the fork because they got so small and nubby towards the bottom. As for the burger, well, we hate to say this but it just wasn't that good. Very bland. We did love the onion component but the bun became pure mush quickly. Honestly, our daughter's plain cheeseburger was better :( We got a couple milkshakes to go, and while we love a thick milkshake, we do also like to have a proper straw for it! So we sat there and had them with spoons. The chocolate one tastes exactly like a Wendy's frosty and the coffee oreo one tasted entirely like oreo (that were pulverized into the shake). Both were pretty good. Bottom line: we're glad we came, but we do not feel a need to be back.

Well... when you think you have found your favorite spot for a burger, and then you run into THIS!! MEAT the chicken fried steak sandwich at SIDS! Oddly enough, the owner was talking with his meat supplier when I walked in, and I got to pick his brain about the meat. All I can say... (without giving away any secrets.) ALL the meat is fresh and never frozen... THAT'S ALL ILL SAY. Most places buy pre breaded frozen steaks. NOT HERE!!. This is a fresh not frozen, large, cubed steak, ran through an old-time tenderizer, then hand breaded. Well seasoned and super tender. Give it a try! It's my new favorite

Such a phenomenal experience! Not only was the burger one of, if not the best I've ever had, my waitress absolutely saved my bacon. Without realizing, I left my company credit card at the restaurant before leaving town and did not realize before I was several states away. Fortunately, Sid's fantastic staff mailed me my card and my employer was none the wiser that I had irresponsibly lost possession! Thank you much!

Sid's is the home of the smashed onion burger and it was tasty! The service was great and very friendly. The location is very small, as I counted a small number of tables inside but they do have a long counter you can sit at and watch them make these burgers fresh to order! There's also outside (air conditioned!!!) enclosed seating as well as some outdoor tables. Very cute spot. Definitely check it out if you're in El Reno!

What can I say? Classic diner in historic El Reno. Just off Route 66, Sid's has earned notoriety from its appearances on many food shows like Man v Food and is featured in George Motz's book Hamburger America. The famous Oklahoma fried onion burger was created in El Reno during the Depression as a need to extend the amount of meat that was expensive and hard to come by. Sid's was not the original fried onion burger but it sure is a great one. Crispy flavorful edges and juicy center. Soft melt in your mouth buns. The service is super Oklahoma friendly. We like sitting at the counter for what the husband calls "a dinner and a show." Fun to watch them assemble the burgers. Sid's is a definite stop if you're looking for a great All American burger. But they also have breakfast items, sandwiches, coneys, and malts.

We just had a very bad (I was going to say horrible) experience at Sid's this evening. We sat down at 6:40 p.m. ordered and drink and our food. The drink was delivered quickly, while we began waiting for the food. Other customers came into the diner, were seated, got their food, while we continued to wait. Our waitress never came by to check on us or tell us what the delay was - we had to wave her over. Then she went back to the grill area and did what seemed to be a rewrite of our order. It had now been 25 minutes and we began to think the food was going to messed up anyway so how much longer should we wait. We chose 5 more minutes and still nothing so we decided to leave for a total of 30 minutes in a place where we saw others sit, order, and within minutes their food was delivered. On the way out, I asked to see the manager who was busy at the grill. An older woman in charge was who came to talk to me and she stated she would take care of us if we would sit back down. She also told me she was face down in the grill busy. I had no confidence is how much longer it would take for that to happen or was concerned if they would even be able to get our order right. When I told her just write a note and we will think about coming back to get comped for such bad service and she would not agree to that. Sid's is 12 miles from our home so we really wanted it in order to make that drive. And you have now lost us as customers. We ended getting a really good meal at Swadley's even though they were not our first choice. If you are monitoring these less that complimentary posts get in the diner and find out what's going on. They weren't even busy when we first sat down and still could no deliver on our order. P.S. I woke up today thinking how in the world in such a small space you can look around the dining room and see there's a table with two people at it that are not eating and recognizing you have delivered food to tables around them that were occupied after the ones not eating. Can't you think "there's something wrong!"

We were traveling through Oklahoma and we wanted to have an authentic Oklahoma onion burger and this place did not disappoint. Nice 50s style diner with old photos of people from the town and hero veterans on the wall which we really respected! The food was great, and the service was also great, no complaints at all. We would come here again without a doubt!

For as long as I've lived in Oklahoma City and as many onion burgers as I've tried, I had never made it to Sid's Diner in El Reno. I had to make an unexpected trip to near Hinton, so I decided to stop for a burger on the way home. First off, I loved the place the minute I walked it. It's pretty small and I wanted to watch them make the burgers, so I grabbed a seat at the counter. You cannot beat the smell of onions on the grill while listening to Marty Robbins sing "El Paso" on the radio. And everyone is so nice. I think every one of their employees stopped by to chat or ask me if I needed anything. I miss that. I ordered the regular, a quarter-pound onion burger with cheese and pickles. I'm sorry, but lettuce, tomato or anything besides mustard just doesn't belong on an onion burger. The King - with two patties - is only $6 (!!!), but after a late lunch there's no way I could have eaten it all. When the meat goes on the grill, it just looks like a small puck. They pile a huge amount of onions on each one, then smash them into the burger. This is so much better than simply putting grilled onions on top of a burger. They flip and smash it again to really incorporate the onions into the patty. The patty is reasonably thin, but the perfect size for their buns. It's the equal of any onion burger I've had. I'm a huge Nic's Grill fanboy, but I don't know that I could say which I like better. As John Wayne said in Rio Bravo, "It'd be pretty close. I'd hate to have to live on the difference." The fries were good too, but the burger overshadows everything else. This definitely will not be my last trip to Sid's.

Was in OKC area. For 20 years we've always made time for stop at Little Mikes Hamburgers. Incredible onion burgers and onion rings. Friends keep telling us to go west to El Reno and hit Sids Diner. Guy Fieri says it's great. Okay we go. What a mistake. Very little and greasy. Burgers cooked in front of you. Kept watching thinking those are perfect flip them. They don't. Ours all went from brown to burnt black. Said something when served. Snarky girl said that's how they do them. Fries soso. Ketchup was excellent. Don't be a hipster. I'm not. But was talked into it this time. Way overpriced for nasty food. Locals at gas station heard us complaining afterwards. Said next time go to Roberts around the corner. Said that's where locals all eat. Sure will next time. Sids is tourist trap. I never was a fan of Guy Fieri but wife was. WAS. LOL

I don't care for steamed or cooked onions. Having said that, I didn't know this was their thing and so I unintentionally ordered the onion burger. I ordered it the way I normally do, with onions, thinking they would be raw. When she gave me the burger she could tell I didn't know that's how they did it and said she'd make me a new one but first I had to try their specialty. I tried it as she looked on with smug satisfaction, sure she was about to have another convert. I thanked her but said I'd still prefer it with raw onions. She was sad. Having said that, the burger was very good, as were the fries. They have an extensive breakfast menu as well so I may have to check in again before I leave town tomorrow.I can see why they were on Man Vs Food.

Great food! Been going here since I was a kid. I love the cheese chili fries and their king cheeseburger with grilled onions.

Hoooo Emmmm Geeee! A blast from the past that will kick you right in the tastebuds! If you looked up the classic American diner in the dictionary, you'd see a picture of Sid's staring at you right in the face. This is the textbook definition of a classic diner and it hits all the nostalgia points. Not only do they serve up one of the best onion burgers in the great nation, but you're basically stepping through a Time Machine back to the past to experience a part of dining that has been lost. Sid's is worth it for the experience alone! Add in the World Famous Oklahoma Onion Burger and you've got a combination that brings you back for more. Classic flat top cooking that every place tries to mirror and it is sitting right in the middle of Oklahoma. We're talking about great ingredients and a passionate chef behind the helm bringing years and years of experience. Before you try to call yourself a burger expert, you have got to give Sid's Diner a try. I mean, I thought I knew how to make an onion burger until I tried this place. So much more to learn. The service is great! The staff are super friendly and your food is prepared by the master and made with all the love! You need to run, not walk, and Go Try Sid's if you have never been before. Just try to take it all in and appreciate it for what it is and I guarantee you will be back again and again.

We were headed back home to Dallas after a weekend in OKC and I convinced my wife to make a 25 minute detour to El Reno. Man, so glad I did. When you pull up to this joint. When you walk in. You instantly feel the history of this place. It's small and quaint and the smell of sizzling burger and charring onions is embedded into the drywall of this place. We were fortunate enough to be seated by the counter so we can get a look at all the action. Let me tell you something, when it comes to piling on the thinly sliced onions, these guys do not mess around!!! Heaps and heaps I tell you. Adam, Sids Diner legacy, even let me creep behind the counter and film him cooking. They even use a special brick mason hardware tool to smash the burgers with the onions on the flat top. Clearly they're serious about smashing the crap out of these things. Looked like a pancake by the time he was done with them. Time to eat. The fries: divine! My burger was straight bliss. Like I never want a burger done any other way again. Just melty cheesy burnt onion meaty goodness! I'm not saying this burger is better than some A5 Wagyu burger you would get for $500 bucks in Michelin star rated New York restaurant. But I'm not saying it isn't either :) Come and enjoy!o

"As Seen On TV" . Yes, stop and eat. Yes, it's worth getting off the interstate. Come on, it's a Route 66 thing and an Iconic Oklahoma Food. Watch burgers get smashed on the flat top by a big spatula that looks more like a bricklayers trowel than a kitchen tool. Watch the videos. Enjoy.

We make it a point to stop here on our way from iowa to Az. We have had the breakfast before so we thought we would try the onion burger,wow what a great burger with thin cut grilled onions and all the choices of vegetables you would want Order fries and was told to order 1/2 order because a full order for 2 people was way too much, great advice and they were great as well Over all the place is 5 red stars and we will back this Spring
