Steadfast Diner

Outstanding lil diner! Farm to table menu with great add on options. Their smash burger is phenomenal! The Steadfast salad has the lightest dressing on it tying the whole thing together perfectly! And the onion rings!!! Oh they are just killer!! Stop in and say hi to Miranda! She is just about the nicest waitress you can find. Such a great place!!

Our new local favorite spot! Had an amazing experience here with our server Nicole. She was so kind and answered all of our questions and had great recommendations. We will be back here very often the cocktails were phenomenal! Have to come back and try everything.

My husband and I first time here. Staff was very welcoming. Not having to cook that night was the best choice ever. Farm fresh everything. Can't go wrong, great food, great staff with a warm environment.

This place was fantastic! Worth the drive if you are far. Great ingredients that taste fresh (local). Atmosphere was perfect. Pretty well priced.

This place has changed my life. I am a smash burger connoisseur and this is hands down the best smash burger in Arizona. We love placing our order online and the food is done super fast. *Eastmark residents can place their order poolside and have it brought to you!! Everyone that works here is really nice and they never mess up our order, (despite several special requests). Inside and outside are always kept clean and tidy, which is hard with the hot temps and flies in the Arizona weather. I have absolutely no complaints about Steadfast Diner, and even though I am totally addicted to the steadfast double burger and onion rings (don’t forget the extra steadfast sauce, it’s insanely addicting), I can’t wait to try the rest of the menu.

Great place to meet with friends, have a date, or take the family and kids. Great vibes. Lots to walk around and enjoy. Service has always been outstanding and food and drink are delicious. They make their sauces in house. We sat inside, but outside was awesome with the misters and games. They have mocktails, shakes, good coffees, etc.

What an amazing little spot! The Steadfast Diner is truly farm to table. The farm next door provides quite a bit of the ingredients and you can really tell from the freshness and taste of the food. The cookies and cream milkshake was amazing. We also had the grilled chicken sandwich and Reuben. Both were extremely tasty. The onion rings tasted farm fresh. Definitely be back!

Great place to chill, drink & eat! I had the steadfast burger, Ruben sandwich & a side salad. I can’t believe the salad had flavor aside from vinaigrette, I could taste an earthly flavor from the veggies grown here! Simply Amazing! My groceries don’t taste this good. The burger was meaty & flavorful but the Ruben was never ending flavor, highly recommend! The servers are ALL friendly, they aren’t forgetful & bring the food & drinks quick! Definitely coming back! You do park on the street & have to walk in, but bring sandals or sneakers because the picnic tables are in a dirt area.

Steadfast diner has some yummy farm to table American food options. I love the steadfast double with the local sourced buns. Food comes up quick and hot. Employees are nice and attentive. Most of the seating is outdoors so plan your visit accordingly. Winter days or spring/fall nights are the best time to visit. Parking can be tricky. Park near the east mark community center if possible or on the street near steadfast farm store. Be prepared to sit on picnic benches which may not be the most comfortable. But food and vibes are worth it.

Steadfast Diner blew me away. The Steadfast Double Burger might be one of the best burgers I've had in a long time -- juicy, flavorful, and stacked perfectly. The Crispy Chicken Sandwich was just as impressive, with that ideal crunchy coating and tender chicken inside. On top of that, the diner itself has a classic, welcoming vibe and friendly service, but the food feels a step above your usual spot. Definitely worth going out of your way for. I'll definitely be back to work my way through the rest of the menu.

I meet here weekly with colleagues either for lunch or cafe/coffee dates. The food has been generally really good and the service has been solid every time. Its all outdoor seating so cone in good weather but there is also plenty if shade when the subs out.. I know my colleagues aways enjoy the alcoholic drinks as well. They have a very good wine/spirits menu, The Eastmark park is always quiet and peaceful where the outdoor seating is.

Came on a Thursday night around 6pm. There was a small line at the order window and a lot of the tables were full. Cute seating area with corn hole for the kids. The atmosphere is definitely their strong point. Total time between ordering and delivery was about 40 minutes. Food was a bit pricey and was somewhat average. The fries were plain. The steadfast sauce and home made pickles were very tasty. The chicken sandwich was dry however the burger was very good. I would return for the atmosphere but not the food.

A small diner with mostly outdoor seating but some indoor seating as well. Service was pretty good and quick. Food wise, I tried the fried chicken sandwich, steadfast double burger, and the farmers daughter (all 3 sides). All the food was very very very salty. The chicken sandwich with the hot honey aioli had chicken that was too dry and not enough flavor (not incl. salt). The breading was ok but it started falling apart. The burger was also very salty especially with the bacon, American cheese, and salty patties. There needs to be some kind of balance with something on the refreshing side, but there just isn't any. The pickles are also salty and the steadfast sauce doesn't do a great job making it any less greasy and salty. The sides were varied in quality. The cheese curds were pretty awful. The cheese was all dried out, chewy, and required you to bite through them with some force. The fries were extremely salty and had a similar problem where it was so fried that it became chewy instead of crispy. The onion rings were the best of the bunch but still too salty. I tried the garlic aioli and the house ranch sauce but both did not do a great job in balancing any of the existing flavors, I probably preferred regular ranch over the house one. Overall, the food makes you feel like you're ingesting diabetes in food form. I would absolutely not recommend this place nor eat it again even if it was free. As a side note, the price is $15/sandwich not including drink or sides. Overall, too expensive, too salty, too greasy.

I got a smash burger and the cheese curds. Both were super good. They have home made ranch that's a bit different but really really good. Get a shake as well.

Our party had the Steadfast Double burger, the Crispy Chicken Sandwich, fries, onion rings, cheese curds and a Coors Banquet beer and a Hey Mama cocktail. We finished it off with blueberry pie and vanilla ice cream. There is ample outdoor seating and misters. Our server showed up very quickly to take our orders. Even though you're sitting outdoors, the service is excellent. Next to the restaurant is a water splash area for kids. Today is was around 100°, so the water area really helped. I have no complaints for this nice restaurant. Perfect for young families with children to have a great meal.

The most amazing smash burger! Burger had caramelized crispy edges and soft/light brioche bun. We had cheese curds with garlic aioli. And music in the park was great. Staff was on top of it!

This business replaced another diner in the same location. Outdoor seating so be prepared for the weather. Lots of seating. They were pretty busy Saturday when we were there but we got seated immediately and our food came out quickly. I got the pastrami double and my wife got the chicken sandwich. Both sandwiches were cooked properly and tasty. The fries were just ok though. Same with the cheese curds. Service was outstanding. The menu is straightforward, salads and sandwiches most.

Service here is excellent. Friendly staff and great food. The vibes are chill too. All the seating is open. Eaten here three times now. During both quiet and busy. As expected, slightly slower turnaround during the busy time but the staff checked in with us frequently and updated us on our food. Stoked to have this near by. Brown rice bowl is a banger. Farro bowl is a banger. Smash burgers are all banging. Ruben is a banger too.

Just had the Pastrami smash burger and onion rings. Simply amazing. Great atmosphere and perfect weather to enjoy lunch. Highly recommend this place.

Such a great spot to take the kids! We love hanging out on the patio while they run around on the big grassy area out front. The food is super fresh and tasty, and the staff is always friendly and on top of things. Perfect place for a laid-back family day

My son and I stopped in for dinner after a play at the park. We ordered an Arnold Palmer and the Farmer's Daughter. This was around 5pm on a Tuesday. Our waitress was very attentive. The meal came out after a little bit of a wait but the food was so fresh I didn't mind a bit. The outdoor seating is perfect for this time of year. They offer cocktails, mocktails and sodas. Plenty of children and doggos were dining too. Overall a great family dining experience.

Burger was great, lil small fit the price, but good. Onion rings great. Ice cream was good, but not $7 good. Outdoor seating in fall was doable. Not a huge menu or a great bargain, but the food was good!

Perfect family friendly environment. Daryl our server was great and super sweet. Food is always good.

Imagine if you had a diner in your backyard...that's exactly the vibe that Steadfast Diner puts off. You're adjacent to the farm and community pool with picnic tables outside. It totally feels like you've stepped out your back door and ordered a burger and fries.... probably because, for so many people, that's exactly what it is. Lucky folks. I dined here with a large group of colleagues recently and enjoyed the smash burger. I've solidly determined that the thinner patty is the way to my heart-not the thick, juicy and often undercooked chunk of meat that I find elsewhere. This one was cooked just right and the flavor was OMG wonderful. I wish I'd gotten pictures, but I jumped in before my camera had any idea what was going on.

Cute diner style outdoor eating area that's great for the family! Somewhat higher pricing but everything is farm to table and the menu is diverse. Good portions (chicken on sandwich was a little small), sauces and drinks were great. We found a table on a Saturday evening and a waiter came right over. The only downside was after we had ordered everything the waiter came back and said it may be a 30-45 min wait, wish they would've told us that before we put our food order in. But we didn't have to wait that long luckily. Lots of people came by to check on our table and make sure we had everything we needed. Definitely will come back!

The service was amazing. We had a super nice server and the staff all seemed very kind and friendly. The pricing wasn't surprising- not cheap but about what you'd expect here. The burger was good, but nothing really special and the same of the chicken sandwich. The sauces were honestly kind of a letdown. The ranch was weird and very buttery rather than dressing texture and the aioli somewhat plain. The appetizers were bad. They were overly salted by a long shot (coming from someone who eats like 3x the daily recommended salt) and they all just tasted like fryer oil with zero nuance or depth in flavor. It's spotless in there with great vibes and a great area but I wouldn't go back anytime soon and they're not a must try.

Review on a Tuesday during Lunch (11:30am) Ambiance & Seating: 4/5 Primarily outdoor seating, so open to elements. Cooler weather when we visited in January. They have space heaters and some seating options in the sun. About 8 counter seats inside. In summer, they have overhead shade and likely will have swamp coolers and misting systems. Available seating and service/wait times were good (less than 15 min from order to being served) Food: 4.5/5 Excellent smashed burger - honestly everything you'd want in a diner style smash burger. Crispy edges, melty cheese, quality toppings. Fries were fresh, salted, and crispy. Grilled chicken sandwich pretty was great! Only recommendation was possibly more seasoning on the chicken itself... however I think the 'less is more' flavor is intentional, similar to Joes Farm grill. The ingredients are fresh and they want that to shine through. So, I get it. I mean like...the lettuce is clearly organic, freshly harvested and grown on site. You can taste the difference. If you've ever grown your own food, you can just tell. If you want more intense flavors, more salt/umami, ask for an extra side of the aioli. It's amazing. Sauces: 5/5 phenomenal. Ranch and aioli dressings were so good it's criminal :') Price: 4/5 Ok. It's not cheap. And it feels like a neighborhood restaurant that's themed as 'diner food' should be cheap, so that's why it's shocking at first. But if you think about the quality of ingredients (local, organic, clean ingredients), paying the staff fair wages in turn for kind, caring, thoughtful service, and supporting its sister coffee shop and farm, I think it's completely fair. I went to a sandwich place the other day and a 8" sub was $18. A burger or chicken sando here is $15. I'll take supporting our neighborhood restaurant over processed foods any day of the week. Grateful for this to be in our neighborhood. Thankful for clean ingredients I feel good about eating, serving to my kid, and recommending to family and friends. This isn't a "we don't have groceries and it's 6pm and we need a quick, easy, cheap meal for a family of 5" situation (although if it works for you, awesome!) This is a "let's go out for a special meal this week" or "I'm working from home and want to splurge on a quality meal for myself for lunch today", and definitely a "it's Saturday night friends!! Let's get a sitter and go grab drinks, a burger, shake, and have a great time!". Enjoy!!

Would give zero stars if possible I understand that Friday nights can be busy, but the way my situation was handled was completely unacceptable. I arrived with a party of twelve and placed my order first -- chicken strips and a side salad. The rest of my group (eleven people) placed their orders afterward. After waiting an hour and thirty minutes, the servers finally brought out my sister and her family's meals, but mine still hadn't arrived. I asked one of the servers about my order and mentioned that I had ordered before my sister, only to be told -- quite rudely -- "We have hundreds of tickets to deal with!" before the server walked away. I went inside to ask about my order, and staff couldn't even locate it in their system. The manager asked what I had ordered, and when I told him, he offered to have it made. At that point, I declined and asked for a refund since everyone else was already eating. He said he'd be happy to issue one, but then completely ignored me. When I asked again as he was walking away, he told me the refund wouldn't be processed until the end of the night. In the end, I received no food, no refund at that time, and by the time I returned to the table, everyone else had finished eating. Very disappointing experience and extremely poor customer service. I hope management takes this feedback seriously and improves communication and accountability with both staff and guests.

PSA: this is not your local greasy twenty-four hour diner. It's infinitely better! They have one of the best fried chicken sandwiches in town. That hot honey aioli is wild. The steadfast salad felt homemade in the best way. The quality of their produce really stood out. Service is fast casual but the staff definitely makes you feel at home. Has been open for less than a week but already is a top shelf culinary experience in the valley

We just found our new, favorite local spot. Omg the food was amazing. My wife loved her grilled cheese and fries. She asked for aside of ranch, which was homemade and delicious! I had the Steadfast Burger, which was incredibly good and a side of onion rings which were just about the best I've ever had. Get them with the garlic aioli, you won't regret it. To top it off, the service was fantastic; very friendly, personable and attentive. Love this place so much. We'll be back often.

Local farm fresh food, server was so friendly and helpful. He was telling us about the events the host and I would love to attend one. We go the farro bowl and ap sampler. Very fresh good food.

Seating outside, seems pretty shaded, but could be warm on an Arizona summer's day. Brianna was our server and seems to be very educated and informative about the restaurant. Food was pretty good and filling. Would recommend. We ate the Farmer's Daughter

Great outdoor dining experience! Food was excellent. Great addition to the area. Will definitely go back. Pet friendly dining as it's all outside. Smash burger was crispy, cheesy and just the right amount of burger to bun and toppings ratio. Fresh fries were crispy and salted appropriately. Rueben sandwich was excellent as well. Will definitely be back!

The food was fresh and delicious. The service was fast and the diner inside was so neat. The milk shake and veggie burger was excellent.

Had the best takeout tonight using their online system...food was ready within 10 mins which was awesome. When I picked it up I was bummed I didn't actually end up eating at the restaurant because it was a beautiful night and nice and cool under their shade and misters. Plus they have awesome margaritas. The flowers on the tables were gorgeous too. Regardless, had the best homemade Veggie Burger, not a gross fake meat one. It may be one of two I've found in the East Valley that is actually fresh ingredients and made in house. My husband devoured his smash burger and my kids are totally obsessed with the grilled cheese and yummy dipping sauces they have. This place is one of our favorite restaurants in the East Valley for sure!!!

Adorable little neighborhood spot with good diner food and surprisingly fantastic cocktails. The Appaloosa Bones might be the best old fashioned I've ever had and the chicken fingers taste like they were freshly breaded in-house. Servers are always smiling, attentive and accommodating.

Ordered the kids chicken tenders to give it a shot - for $10 - 2 nice pieces of perfectly crispy chicken and ample amount of perfectly golden crispy salty fries - the homemade ranch is perfect for chicken and fries - so now I will be back to try burgers and onion rings and maybe get their crispy chicken sanwhich to go !! Place was busy but staff was on top of it !! Check this place out it is a sure winner for your taste buds!!

Stopped by to check this place out. I had the Steadfast double burger and it was fantastic. I'll definitely be getting it again. The burger doesn't come with any sides so you have to order them separate. The server seemed knowledgeable about the food and it's origins and he is the one that recommended the burger -- I'm glad he did. They do have a selection of beers on draft. Sitting outside this time of year can't be beat!

super fresh & yummy food! they are new which was obvious. there are definitely some things like speed of service that hopefully improve by our next visit, but overall the staff was very friendly and the food was so good. love the cute diner feel while still being able to enjoy the outside!!

Met a few friends today for lunch. We ordered a burger, Rueben and the cheese curd/onion ring mix. The service was very spotty. We had to repeatedly ask for things like water and napkins. The young man who served us must have been new. He seemed overwhelmed and a little confused. The food was super delicious though. The onion rings were small but beer batter style- my favorite. The Rueben had scant meat, but I like them with less meat. The burger a friend had looked great and she enjoyed it. There are only picnic tables to sit at and it's outside seating. There is shade available. Prices are on the high side, but it's so fresh it's was worth it. Overall we really like it. I'd be worried if it were crowded with that server that it would be a frustrating experience. We will go back though.

Our favorite spot to go for a chill dinner with our family. The kids love running around in the grass. The cheeseburgers are always a hit for the kids. My husband loves the crispy chicken sandwich and I love the burgers (+gf friendly bun!) and prickly pear margarita.

$15 for a tiny crap burger with no fries. Also ordered shakes and they were not good, service took forever and messed up our order each visit. Won't be visiting again. Also read this place didn't pass health inspection so that's no bueno.

Disappointed! We were looking forward to this being a decent place just down the road, but there is no reason to go back again. We tried twice a few weeks apart with no luck. Poor quality, poor service and overpriced. Honestly, I wouldn't mind the prices if the food was good, but that was not our experience. Pros: location Cons: everything else

Food was excellent and the ambience can't be beat! Cheese curds were delicious. We'll definitely be back.

We tried the rice bowl, Reuben, and chicken sandwich burger at Steadfast Diner. Everything was flavorful and well-prepared, and the portion sizes were okay--not too big, not too small. The Reuben had a nice balance of flavors, the chicken sandwich was crispy and satisfying, and the rice bowl was a solid choice. For appetizers, we ordered two of the Farmer's Daughter. The flavors were great, but we were hoping for more onion rings and cheese curds--most of the plate was fries, which was a bit disappointing. One downside is that there's no restroom inside, though a public one is nearby. Not a dealbreaker, but worth noting. Overall, a good spot with tasty food, though a few tweaks could make it even better!

Way too much sauce in the burger, which is something I never thought I'd say. But I'm a huge burger fan, and these burgers were gross. What's with the skinny patty that is way too large for the bun, and then it's drowning in sauce on top of it, so it's impossible to eat, falling apart, and a mess. Also, just doesn't taste good. This is the worst burger sauce. Not a fan.

Amazing food and service. Enjoyed a nice dinner while kids also played in grassy area next to us. This place will be a go to when visiting Mesa, AZ. We had classic burgers, chicken sandwich, fries, two kids meals. All delicious.

I understand it can get overwhelming sometimes with a fast food restaurant , but we waited 2 hours for 3 chicken strips that was soggy and cold and a side salad, that was too salty to eat. services was down right disrespectful when asked about our orders.

I know it's Friday but ordered took 14 minutes to get drinks and 45 minutes to get food. The food pastrami was hot and tasty, salad was $$$ and small portions. I would give it one more chance, I think they need a bigger kitchen to handle orders

We are so fortunate to have this restaurant right there in Eastmark! We order take out or stop in for a bite almost once a week at this point - the food is great quality & delicious. The service is fantastic as well. Tonight when I went to order online and got an error message, I called in and they picked up on the second ring and took care of me right away. We love the burgers but the salads are delicious as well!

Steadfast is truly great farm to table food in the heart of Eastmark. Our family has been a few different times and the food is always incredible. Since opening it looks like they've worked out the service kinks due to demand & staffing and our last couple visits have been pretty efficient and timely, but certainly not a place I'd go in a time crunch as the kitchen is very tiny and apt to get backed up during the dinner rush. Overall, it's tough to beat some great outside dining in Spring in AZ the menu and drink list is incredible and work well together. Can't wait to head back

Really bummed about this. The pastrami burger wasn't bad, but not at all worth the price. Burger, fries, and shake was ..... $34.00! Far too expensive for a hamburger lunch. Won't be back.

Saw a post about this places farm to table style burgers and wanted to try them. Drove out to Eastmark after a workout and it was totally worth the drive. Somewhere I'll be back and bring people to. Servers were helpful right away, you can seat yourself. It's a cute little place with plenty of outside seating facing the park so also lots of open space to run or picnic too. Food was awesome! They make everything in house and I mean everything. The ketchup the mustard the ranch and the burger sauce too. They have great shakes too my gf got a cookies and cream shake and it was delicious. A cute place to enjoy good grass fed burgers and a drink. Nice and clean space with a homey feel to it. Check it out! Good stuff!

This place has changed my life. I am a smash burger connoisseur and this is hands down the best smash burger in Arizona. It has been a staple in our house since it took over the Handlebar. We love placing our order online and the food is done super fast. *Eastmark residents can place their order poolside and have it brought to you!! Everyone that works here is really nice and they never mess up our order, (despite several special requests). Inside and outside are always kept clean and tidy, which is hard with the hot temps and flies in the Arizona weather. I have absolutely no complaints about Steadfast Diner, and even though I am totally addicted to the steadfast double burger and onion rings (don't forget the extra steadfast sauce, it's insanely addicting), I can't wait to try the rest of the menu.

We saw the Fox 10 morning news report on Steadfast. The food looked amazing. We love the concept so went early afternoon. It is a very cute venue for Eastmark Park. All outdoor seating...you would not be able to dine in the summer. The food was nothing as it appeared on TV. I ordered the smash burger. The two paper thin patties were not visible outside the bun as shown on the news program. It was tasty but very small for $15. I don't think the meat totaled 1/4 lb. Mostly bun and sauce. I couldn't even taste the homemade pickle and very little lettuce on board. My husband ordered the fried chicken sandwich. The chicken breast was so small the bun hid it. Not the huge crispy breast presented for the TV show. He said the chicken was very dry. Disappointed for $15z We ordered the farmers daughter ($12) which is a basket of fries, cheese kurds and onion rings. The cheese Kurds were really tasty. The onion rings were very thin and small. Definitely not the large rings shown as a side on the news program. The fries were leftovers. They were just small pieces. So small you couldn't dip in ketchup. Very disappointed in the portion sizes for the price. We ordered a coke and an Arnold Palmer. The Arnold Palmer was $4.50. Mostly ice in a grande size cup. No sweetener available on tables. I had to ask. There were no servers around to wave down. They go hide behind a gate. My husband asked for a refill of his Coke when we were almost finished with lunch and they returned with plain ice tea. Ridiculous. Service did not deserve a tip. Yes, I left one. I want for this to be a success, cute idea, but I don't see it happening. You can't make magazine food for a TV ad opportunity and then make subpar food the same day the news report aired. $63 for lunch with the tip. Ridiculous. Won't be back.

The food was good, no complaints there. But the service could've been better, our waiter wasn't very attentive and forgot our drinks. We ended up having to grab our own to-go boxes and waited quite a while just to wrap things up. Just felt a bit unorganized. Very cute diner.

Food was good! I had their Steadfast double smash burger and the sauce was awesome. You also need to get their onion rings for sure! But our waitress Avery just made our dining experience wonderful. She was very attentive, friendly and quite bubbly!! We sat inside the bar area , which was very tight and small but it's better than outside where it was 104 degrees this afternoon ..... but they do have misters outside that helped. Oh and their affogato was a scoop of vanilla ice cream and a DOUBLE shot of espresso where most places only pour 1 shot! Bravo!!
