The Original Hills Kitchen

I ordered the Jalapeno hamburger and my daughter and husband ordered the Hills hamburger. I really enjoyed my burger, house fries and the ketchup was amazing... it wasn't traditional heinz ketchup. The French fries reminded me of homemade fries. They were really good. My husband also enjoyed the burger but he said he wished the meat was seasoned. My daughter said the burger was perfect and that it had the right amount of sauce on it. She didnt think the meat needed to be seasoned as she said the sauce made up for it, as it was full of flavor. The service was also good. I'll definitely return the next time I'm in Ontario.

I'm glad I finally tried this little hidden gem. I went with the Thai Beef Steak sandwich and upgraded my side to the truffle fries. The fries were crispy and seasoned perfectly with truffle and Parmesan. The sandwich is similar to a banh mi. It was filled with plenty of steak, cucumber, carrots, and cilantro. It was topped with a flavorful ginger dressing. You order at the counter, and if you are eating in, they bring your order to your table. They have a few indoor tables and also seating outside in the covered patio area. I also recommend getting one of the craft sodas they have on tap. The Pineapple cream soda hit the spot.

Dropped in for sa burger fries & a coke. Sat by the window. What a view, mountains through the greenery. The air quality and temp were perfect so I moved to a North table. Classy, clean and welcoming. Both the burger was exceptionally good. And something I couldn't identify name the fries even top notch. Going back to try the (loaded) chicken club sandwich on artisan bread.

Hills Kitchen is hands down one of the best burger spots I’ve ever been to! From the moment you walk in, you’re welcomed with a warm, inviting atmosphere and a team that genuinely cares about your experience. The burgers are absolutely incredible — juicy, flavorful, and cooked to perfection with fresh, high-quality ingredients. Every bite feels like it’s made with passion. The menu has something for everyone, whether you’re craving a classic cheeseburger or something a little more adventurous. Their homemade sauces and perfectly toasted buns take everything to the next level. Sides like their crispy fries and hand-spun shakes are the perfect pairing. If you’re looking for a place where every visit feels like a treat, Hills Kitchen is it. I can’t recommend it enough.

Jalapeño burger was juicy and bursting with flavor. I think this place is a little better than Eureka. I’ll be back to try the other interesting burgers and sandwiches.

Hills Kitchen is the REAL THING!! Wonderful food in a nonsense store front. Be prepared for one of the best hot sandwiches you’ve had in a long time! The burger was PERFECT as was the wonderful soft bun. Lettuce was fresh and crisp. We chose a solid Caesar salad as a side. Service was fast and friendly. We will be back on our next trip through town

Awesome joint. Great burgers, sweet potato fries are awesome, but drop the honey on them, it's not needed. Burgers cooked to perfection, we enjoyed our visit.

Wow!! First time visit as we were on a road trip. Very high quality meals that didn’t disappoint. They must be using high quality ingredients and they certainly know how to prepare and cook as well as how to present the meal. Small place with small’ish tables and a counter type seating. More seating capacity on the outdoor patio. One employee who appears to be serving all roles (greeter, order taker, cook and server). Real plates (not paper or plastic), flatware, etc. we had the Hills Burger and the Hills Sirloin Salad both of which were incredible. I’d definitely have the Hill Burger in a repeat visit.

the food I tried is pastrami great and Munchy, the service was clean and fresh, thank you.

Unreal... can't believe there isn't a line every opening hour of every day... prices similar to like a casual restaurant (chilis, Applebees, BJ's etc...) $12-20... extremely cheap for the quality you get in every meal. I know $15-20 can sound like a lot for a meal... but in September 2025, go to a fast food restaurant & get a numbered meal, regular sized even and it's like $14-16... this is actual high quality and honestly too fair pricing. I'd be happy to pay a little more just because I know they're only this cheap for us... clearly the quality outweighs the price by a long shot... I went for the first time a few days ago for the regular cheeseburger, comes with fries.. amazing... gonna go now for the Thai burger or chipotle chicken (insane reviews on that one)

So clean friendly and the food is fresh and ohhh soooo tasty! Working my way through the menu, but so far, the West Side Burger is my fave! You won't be disappointed!

I haven't been here since my first review in 2022 but I have always wanted to come back and I did yesterday. With that being said, everything was delicious. The truffle Parm fries are amazing. Excellent flavor and just the perfect amount of crispy. I got the hills burger and although I didn't get a lot of the gorgonzola flavor, the patty was seasoned nicely and the bacon and mushroom and the hills sauce was delicious. I definitely will make sure not as much time passes for my next visit.

This was our third time visiting, and as usual, the experience was amazing! The staff welcomed us in immediately, rushing over from the back to the counter when we stepped in. The employee (owner?) even gave me a free drink on the house, saying he will buy my drink for me, which was so sweet! The cashier/waitress even delivered our plates to our table, and gave us homemade ranch (it's one of the best I ever had) & ketchup My brother had the West Side Burger, my bf had the Hills Burger, and I had the chicken pesto sandwich (upgraded my fries to truffle frenchies). We all loved our meals so much! My brother, who said he wasn't that hungry, devoured the entire plate (even though the portion was quite large). My bf said his burger was juicy and the fries were very well-seasoned. My sandwich was exactly what I was craving: the bacon was perfectly crispy, and there was an abundance of chicken. The truffle fries were addicting, with plenty of truffle and parmesan We came at nighttime, so it was very quiet and calm! The restaurant was clean, nicely decorated, and very cold from the AC so bring a sweater We're looking forward to coming back again :)

While visiting Alta Loma HS for a water polo tournament, we had time to grab lunch nearby. This place has a good star rating because their food is good! Their fries have that fresh cut taste with the right amount of salt and the chunky ketchup is a perfect dip. I had the Pastrami sandwich and switched out the aioli and it was wonderful. The boys had burgers & fries and love theirs as well. Also, they have black cherry soda on the fountain.

loved this place! The sandwiches and fries were incredible -- super fresh and flavorful. The team goes above and beyond to make sure customers are happy. Highly recommend!

I love the hills kitchen burger they have here. Service is a little slow. But they have only 1 guys running the cash register taking orders, dropping off the food and cleaning the tables. So if they get busy, that guy is running around extremely busy!! Sitting outside in the shaded area is really nice. Just you get the exhaust and fumes from some of the cars at the drive thru of Del Taco. The hills kitchen burger is amazing! High quality ingredients. Even the bun is amazing. The patry is thick and juicy. The sauces are amazing and pairs well with the entire burger. The truffle fries are super crispy and you definitely get the truffle flavor. They did get rid of the actual sodas for the soda fountain. And replaced it with other carbonated drinks. The cherry and other one was good. But the root beer had no flavor what so ever. But definitely a solid burger joint!!

First time visit and enjoyed chicken pesto sandwich, side salad, and pineapple cream side. All very delicious and exactly what I was hoping based on the current reviews and photos. The service was nice and place was clean. I will be back!

Hills Kitchen is an awesome local burger joint serving up some American comfort food classics with their own twist! This spot is located in a plaza with a good amount of parking spots. Inside, they have about 3-4 tables for seating and a nice outdoor patio area with about 5-6 more tables. As for their menu, they have a nice selection of different burgers, sandwiches, salads, and more! Wifey and I stopped by for lunch and decided on the Hills Burger and the Miso Salmon Salad. The portions were very generous and everything tasted fresh and elevated! Overall, we are glad we got the chance to check this spot out! All of the staff here are very friendly and accommodating. Come stop by and definitely try one of their burgers and you will not regret it!

Walked in today. Looked up lunch in the area. Saw the home made looking burgers. Had to try it. Walked in and ordered. The gentlemen that took my order is super nice. Opened doors for elderly ladies. Ordered and man.... Ceasar was refreshing and amazing! Then the burger, after biting it brings a smile to your face. Outside patio is stunning.

Food was really good, you can taste the quality definitely! Service was a little slow, I would say we waited 15-20 minutes just for two burgers, drinks are self served. Ambiance is pretty calm, small space though, good thing there is outside seating! Definitely would comeback here.

This was our first time trying out this burger joint. We ordered the Jalapeno burger, the Chicken Chipotle sandwich, and of course we had to also try the Hill's Kitchen burger. Out of all 3, the Hill's Kitchen burger was the best! It was juicy and flavorful! The Jalapeno burger was pretty good as well, but I wish it was a little spicier and had some crunch. Fried onions or crispy onion rings would've been a great additional if that wa an option! For the sides, we upgraded our fries to truffle fries and it was so worth. The truffle fries were very delicious. Overall, great burger joint to grab a quick bite. This spot is located within a plaza so parking was very convenient and quick.

My wife and I love coming here when craving a hamburger. Best gourmet burgers around. It always clean, staff friendly and a relaxed atmosphere.i enjoy sitting outside seeing the Cucamonga peak. Never disappointed with any of the burgers. Also love their side salad or fries option that comes with it.

Good food great service could not ask for more! My favorite spot to get a chicken Caesar salad and they're known for their burgers, which are also delicious.

I don't know how this establishment has the ratings it does. I came here last week after seeing it and checking it out on Yelp. What a disappointment! There's literally not one thing special or good about it at all. The sandwich was fine, nothing I would let someone know about. Sat on the, "cozy" patio to eat since there are only a couple tables inside. What a drab and dreary patio. The planter boxes are full of pine needles, overgrown and unkempt succulents. Pine needles all over the floor and spider webs on the chair legs. It's very obvious to me that whomever owns this place isn't that dedicated to it at all. The lack of attention to detail on what could be a great outdoor space is neglected and tells me the restaurant is a hobby and not a passion. Take it for what it is worth. I won't be returning and would rather spend my $20 on a sandwich at a place that cares.

One of the best burgers I've ever eaten... delicious, juicy... the fries were perfect and their sauce was perfectly spicy! Highly recommended if you want to try a different kind of burger. We definitely want to go back!

Hills Kitchen: where the fries are golden perfection and the cheesesteak is...well, more like a game of hide and seek. Let's get one thing straight: do NOT come here if you're hangry or in a hurry. The food takes a while, but that's because they're actually cooking it, which I hear is a rare and beautiful thing these days. Patience, young grasshopper. Your fries will thank you. Speaking of fries--chef's kiss. Crispy, salty, hot, and fresh like they just got out of a potato spa. Honestly, if Hills Kitchen sold these fries out of a van in an alley, I'd still show up and probably bring friends. They are THAT good. I've had the burgers--they're solid. Nothing to write home about, but definitely something to eat at home if you live nearby. Recently tried their cheesesteak, which was bold of me. The meat was elusive--like it had read the menu, panicked, and tried to escape. It was a cheesesteak in spirit only. I think I caught a glimpse of beef, but I can't be sure. It may have been a mirage. All in all, Hills Kitchen is a reliable local spot. Just lower your expectations for the Philly experience and raise them HIGH for fries. If fries were a religion, I'd convert here.

I'm surprised at all the high ratings. We had the Hills burger and a jalapeno burger. Both super dry. Sorry to say very disappointed.

We saw this place on yelp and had to try it. We arrived about an hour before closing but the cashier was friendly. We ordered the cheeseburger and the jalapeño burger with fries. The meat was cooked well done so in some parts it was a little dry but the flavor was pretty good. The steak fries were really good. The shop is on the smaller side but there's a lot of outdoor seating. There's plenty of parking. Overall we would go back but not so close to closing time.

Stopped by for an early lunch at Hills Kitchen. Great customer service, couple of tables inside and outside. Ordered the breakfast burger - Chuck, smoked mozzarella, fried egg, romaine, roma tomato, red onion, hills sauce, ask for the chipotle sauce on the side. Very delicious burger. Crispy side of truffle fries

Came here for lunch with my husband and momma in law. We each got different menu items. We all loved our meals. Location is nice and easy to get to. Parking might be pretty busy, as it's in a AAA & Sprouts parking lot. The inside of the restaurant has 2 tables and a cute little bar to sit. The outdoor seating is very big and nice but it was a bit chilly today. We sat at the bar table. I chose the Hills Chicken Club, added pickles. My husband chose the Hills Crispy Chicken. My momma in law chose the Pastrami au jus. We all chose fries for our sides. My sandwich was made perfect. It was so delicious!!! The fries were tasty and perfectly salted!! I tried my husband's crispy chicken sandwich and it was just as good!! My Momma in law offered me a bite of her pastrami but I was too busy enjoying the wonderful jams & my delicious sammich!! I loved the music they had playing!! I was trying to not dance in my seat and sing along. Hahaha!! We had a great lunch here!! So happy we finally stopped by this local gem!! So sad it has taken us so long to come by!! We already talked about what we want to try next time!!

Miso Salmon Salad is delicious . Definitely will be back to try the burgers! Next time!

Absolutely delicious! An affordable gourmet burger. Will definitely be returning to try their salads!

Always delicious. When we order there we try something new. It gets better each time. The burgers are the best in town. The pastrami is outstanding. Everything is so fresh. Service is so pleasant & it's a cool little hangout.

Food is excellent! Service is great and ambiance is welcoming! Friendly staffs! Their jalapeño burger was good too and the spicy chicken sandwich, chipotle sandwich too! Just try em all out!

4 Stars - Tried the Hills, Jalapeño, and West Side burgers-all delicious and full of flavor! Easily the best burgers in the area. Only downside: limited indoor seating, and the outdoor area was too cold even with heaters. Will definitely recommend to F&F!

Tried this spot while visiting the area because of the good reviews. The employees were friendly and it was very clean. I ordered the spicy chipotle chicken sandwich and it was really tasty. Loaded with flavor and did not disappoint. It was also not too spicy but just good flavor. I would definitely order this again. My boyfriend ordered the fried chicken sandwich and it was a different story. It was very basic fried chicken with some jalapeños and honey on a bun. If you like friend chicken sandwiches I would not suggest ordering it here. Overall, I would go back and get the spicy chipotle chicken sandwich.

Best burgers in Rancho Cucamonga by a long shot. The Hills Burger and West Side Burger are my definite favorites. So good in fact that I've never bothered to try anything else out of fear that I won't like it as much as my standbys. I am happy to say that their fries are really good as well, so you won't have to worry about being letdown. Service is usually really friendly. The place is smallish inside, but they also have patio dining as well.

Im really surprised by all the 5 star reviews. The cashier was super friendly and the place was clean, but thats it. I ordered the Spicy Chipotle Chicken sandwich and it was flavorless. The fries weren't the worst, but they weren't good. Half the fountain drinks were out of order but they did have can options available. $19 and I stared out the window wishing I would've gone to Del Taco

Ordered, my food and was served a fresh and hot jalapeño burger within 10 minutes. The fries were a surprise, they were probably the best part...something great is happening here. Food was brought out to me, great service. I sat on the covered patio which provided a comfortable place to eat. I will be going back.

Food 4/5 Probably one of the better burgers I've had in Rancho. I had the signature Hills Burger. It has gorgonzola and bacon. I was a little skeptical, as it's been a while since Ive had a gourmet burger. But I was pleasantly surprised. The gorgonzola gave it a really deep flavor. The bun was soft and the meat was cooked perfectly. The fries were fresh/hot, crispy on the outside with a little seasoning and soft on the inside. I'd love to come back and try their classic. Service 3/5 It was fine nothing memorable. We ordered food, they brought it out. Their fountain machine was down, so only canned soda/drinks available. The restrooms were very clean. Ambiance 3/5 The interior was small and they had TVs going with some sports. We sat outside, just note they are close to the road and right next to Del Taco's drive through. The outdoor seating is pretty close to eachother, you probably couldn't have a too private conversation without those sitting right next to you not being able to hear. Overall, I'll be back. It's not cheap but it's a quality burger that I think is price perfect without me thinking it isn't worth it.

A hidden gem with exquisite food and a cozy, refined atmosphere. The dishes are perfectly crafted, beautifully presented, and full of flavor from the rich sweet potato fries to the perfectly cooked burger meats. Thoughtful details, like elegant plates and silverware, elevate the experience. Impeccable service adds to the charm. Despite its tucked-away location, this spot rivals the best fine dining in the city. Highly recommend!

Food was DELICIOUS! I had the crispy chicken sandwich and sweet potatoe fries...and it was excellent. Chicken sandwich was flavorful with great sauce and the fries were delicious and drizzled with honey! My wife stole almost all of them from me! We will definitely be back!

Delicious and fast service. However sometimes the order is wrong when you order over the phone but Al's not always have a great experience. The sandwiches are the best.

We can't believe it wasn't more busy. Super clean, modern space. Although we didn't sit outside, it's super nice out there. My husband loved his burger and I tried it and loved it too. It was the Wedtside. Good quality ingredients. My salad was really good too. My only suggestion would be to add a pinch more salt to the chicken. The chipotle flavor was on point though. I'll definitely try a burger or hot sandwich next time & we were able to catch a bit of some college hoops too which was nice.

This restaurant has always been 5 stars. After a recent visit, i thought there was a change in ownership. It wasn't the same burger they always served. There was no taste, no seasoning, and it was a smash burger. Their old burger was a thick patty and it was absolutely delicious. Also, I observed, no gloves being worn anywhere. The young man at the register also goes into the back kitchen and after, bringing our meals to the table. We always love supporting small businesses in our own community but I do not think we will be returning

We stopped for lunch before flying from Ontario International Airport. These burgers are perfection! The service is great. The buns are perfect for burger lovers. Fries are perfect as well. The lofi music jams is great too!

Plenty of parking spots! This burger joint is a fairly small restaurant, but it does have an outdoor patio, which is pretty nice! Definitely a nice sit-down burger joint and it's pretty modern. The vibes and interior remind me of a ramen shop, especially the way they play lofi hip hop. Ordering process was easy, you order at the cashier and they bring your meal to the table when it's ready. We ordered a classic cheeseburger and a jalapeño burger for that day. Loved how clean the tables and chairs were! It didn't take too long for our meal to be ready, so it was pretty quick. The hamburger were tall, and the fries were THICCC. I actually like these type of fries the best. The fries were done really well. We also got truffle fries as an upgrade and the taste was a bit subtle? It does seem like all the truffle was very centralized to one part of the fries, but I feel like they could have tossed it around more so the entire fry can taste like truffle. The hamburger itself was also really good and cheesy! The ingredients they used also tasted very fresh. Really enjoyed my experience here! Would go again :)

Love their chicken pesto and fries. Husband loves the Thai beef. Definitely our go to for to-go when we have company over - always fresh and doesn't disappoint.

This place is a gem, especially for the price. The burgers are absolutely terrific--some of the best I've had, and that's saying something, considering they're gourmet burgers. The consistency is impressive; every time I've gone, the quality has been spot on. The flavors are well-balanced and delicious, making each bite a real treat. The ambiance is okay--nothing too fancy, but it gets the job done. What really matters here is the food, and on that front, this place delivers. Please deliver to my house lol jk. In a city that doesn't offer much good food except for chains, this place stands out as one of the better spots. I'll definitely keep coming back. Highly recommend it!

I visited here during a recent business trip to Fontana. It was a short drive from my hotel, and I'm glad I decided to venture out a little as opposed to eating at one of the many overpriced restaurants by the Mills mall. It's a small place with a small menu on the wall behind the register, but they do have a modern interior. Most of the seating is outdoors on their patio and that's where most other customers were sitting. I opted for indoors in the ac. They have fountain drinks, but if you want iced tea, it is bottled. I ordered the jalapeno burger, upgraded to truffle fries and a bottled sweet tea. They did not ask how I wanted my burger cooked. I didn't see an option for adding a patty, but I imagine you can for an added cost. The burger itself seems to be about 1/3 lb fresh, but machine formed and highly compacted. The bun to meet ratio is slightly high...I enjoyed the fresh cut fries. The burger itself is pretty good.....this is definitely not fast food quality...but served fairly quickly. The jalapeños did not make this burger spicy in the least. It's a decent option for a fresh burger in the IE, but it doesn't quite stack up to the fresh burger places back in Texas, with a looser hand-formed patty and that greasy taste. I would visit frequently if I lived in the area though, as it is light years better than In n Out, for example.

Absolutely. One of the best spots around. I've been a handful of times so far. The fish & chips, the cheeseburger is what I've had so far. I go back and forth because they are both really good. Very nice people who work here as well.

My Cesar salad was very yummy. A lot of food! I also order the chipotle sandwich the sweet girl on the phone recommended. Quality was pretty fair. One meal can definitely feed two. Or split up throughout the day. Thank you again! I will be ordering the Cesar salad more often :)

Heck where do I start you want to taste a quality burger you should come here. Put a in and out burger next to it and hills kitchen will surpass it no problem you can taste a well made burger. This guy has a passion for cooking it tastes awesome recommend the classic cheeseburger or if it just when they opened go with the breakfast burger it will not disappoint. I recommend these burgers 100%

Food looked so good on the pictures needed to try it. Came in had the West Side Burger. Had the bbq on the side. Everything about it had killer flavor. Also had the Herb Beef Cheese steak. Put the chimichurri on the side because I didn't know how it would fair in flavor. It was very good. The fries very good. Love that they are hand cut style. The staff very friendly. The location is a bit small not a full sit down. It's more of a take out feel with tables so do not expect sit down service. That I don't mind. Especially when I am just wanting something quick. Reasonably priced and good flavor. This place rocks. I'll be back for sure.

Oh my gosh! These burgers are AMAZING!!! I'm a total burger girl and I gotta say these are some of the best burgers I've ever had if not the absolute best, every single ingredient is top quality and the service is unbeatable. Each time we've gone we've been impressed with the good food and great service. This business truly cares about their quality and the customer experience. I tell everyone I know about this gem. I haven't tried the sandwiches yet but my husband has an said they are just as good as the burgers

The most beautiful, flavorful, delicious burgers. We ordered the Jalapeno Burger, the Hills burger, the West Side burger, truffle fries, and sweet potato fries. Everything is amazing. I do not usually take pics of my food or leave reviews, but this deserves it.
