The tenderloin sliders were so good! I love a tenderloin but it's usually a commitment. These bite-size sliders were just the perfect amount. It was super busy on a Saturday around 5pm but we got our food quickly. Everything was delicious! All of the staff were friendly even though they were busy. It is on the smaller side inside but they have tables outside as well. Loved the vintage decor and the Three Stooges playing on the tv. I would definitely go back for the tenderloin sliders and to try their desserts as well. read more

We both got their handcrafted root beer which was a treat. We both really loved their tenderloin because it was that good. We got the appetizer combo with fried pickles, mozzarella cheese and onion rings but for some reason the onion rings weren't as good as I remembered them to be the first time. Service was good. read more

This is a true gem in Plainfield and I see why it's so popular and I see many great reviews. I love that traditional diner feel with lots of decor. Menu offering breakfast, lunch and dinner options (breakfast served all day!). And most importantly, it is affordable! They are not overcharging the customers and it is nice to know that you can eat a meal for under $15 in 2026. Our server was friendly and patient with us first timers. Service and food were on the slower side but I enjoyed dining here read more

I ordered grits, avocado toast, and herbal tea. The avocado toast spread didn't have big chunks of avocado. It was a little more like a guac. I believe it had feta cheese, but now I don't remember. The server was so nice. She showed us an informational sheet on the history of the diner. She made recommendations for local things to do and times of year to visit. read more

Oasis Diner - Meat Lovers Omelet - Diners Near Me - Plainfield, Indiana

Almost 2 years after my "discovery" of Oasis Diner, I've probably been here so many times now! Therefore, I know more than I did before. Food is always delicious. I've gotten breakfast here twice, and we're normally here for dinner. Prices are always really good and we can get a good value for our meals. As of late, I've discovered their cappuccinos which either can be flavored with French Vanilla or English Toffee. I'm partial towards the toffee flavor since I like the complexity of the toasted caramel notes. Our servers are always really friendly. I believe the servers are mainly around student age, so it's nice that they can get good work experience. Because they're presumably underage I don't want to list anyone in particular for a special shoutout, but I can give them all a blanket shoutout of positivity! The atmosphere has more retro elements than I first realized, with a whole wall of vinyls and 8-tracks. There's also a nice mural with Indiana license plates so you can see the design evolution. The road map with a few different highlighted cities is also pretty neat. read more

Best tenderloins in Indiana hands down! I love the seasoning of the tenderloins, it's my go-to every time I visit. The server was great, lunch was amazing! I love the hospitality of this place. My mom & I used to go here when I was a kid at the old location they moved the place from. I love the new location with the same great food & service. I've been here for breakfast as well & it doesn't disappoint either. Stop in while you're in town, you won't be disappointed! read more

Fantastic service. Tasty tenderloins. Food sides. Drinkable sweet tea. Decent prices. read more

Oasis Diner - Diners Near Me - Plainfield, Indiana

Dinner at Oasis Diner was such a cute, nostalgic surprise. The walls are covered in cassette tapes, vinyls, CDs, and 8‑tracks, and the dessert counter looks straight out of the 1950s. We had the tenderloin, tenderloin sliders, fries, onion rings, and fried green tomatoes -- and those fried green tomatoes were the best we've ever had. The tenderloin was great, fries were perfect, and the shakes were delicious (just smaller than expected). Onion rings had good flavor but were a little chewy. Service was decent. Overall, a super charming spot with standout comfort food. read more

Oasis Diner - Vanilla milkshake - Diners Near Me - Plainfield, Indiana

I found this diner on Tik Tok so I feel like I HAD to come visit. The place was busy as I expected and the inside was decorated so cute and vintage with records and cds and pictures and old games plastered on the walls. Our server was so nice and patient with us as well. I ordered the special they had which was some waffles that had ice cream and caramel and pecans spread on top, and a side of grits and my boo ordered avocado toast with hashbrowns on the side. The food was delicious and the ice cream was an added touch to the waffle. Felt like dessert for breakfast but that's exactly what i was craving 10/10 Will have to come back read more

Standard diner food, the pork tenderloin is by far the star of the show, service can be hit and miss at times, nice nostalgic feel and ambiance read more

My husband has never met a diner he didn't want to try, so naturally we had to go to the Oasis Diner when we visited Plainfield. It originally opened in 1954, according to the mural outside, and it is a quaint, cozy and delicious little spot with quick, friendly service. We tried the Oasis burger; the short stack meal; the Quaker breakfast; and the Indianapolis country-fried breakfast. The portion sizes were generous -- our teenager couldn't finish the double-patty burger -- and everything we tried was tasty. Our kids especially liked the housemade sodas! We only had two minor issues: The booth was a little *too* cozy for four fully grown folks, and I wish we'd saved room for pie! We might start with a piece of strawberry-rhubarb next time. read more

Was there earlier about 1130 a.m. Got a burger and onion rings. Burger was ok, but those Onion Rings were AWFUL. Were very tough and didnt have an onion taste to them. read more

Well, we stopped in here on our way back to Kentucky from Plainfield, this place. This place was originally opened in 1954, according to the mural outside. The place was busy. Despite that, the staff was very attentive. I just love the decor of vintage records, pictures, and old games plastered all over the walls, giving the 1960s dinner feel. I had the Oasis Burger, which is a double burger with pulled pork, bacon, BBQ sauce, coleslaw, pickles, and cheddar cheese served on a brioche bun, while my wife had the Quaker Cheeseburger, which is served with American cheese, lettuce, tomato, onion, and pickle on a brioche bun. She added bacon as well. They are all served with your choice of regular side and a pickle spear. I had the onion rings with the Sriracha ranch sauce, which is excellent; my wife had her onion rings with ranch. We both had Beignets for dessert. Be sure to try out their root beer, as it was delicious!! read more

Oasis Diner - Diners Near Me - Plainfield, Indiana

I can't tell you how many times I have been to Oasis over the past year-and-a-half since I've discovered it. Every time we walk in, we are immediately greeted by the cheerful staff and warm, retro ambiance. There are so many things I love about Oasis, but I think the biggest thing is the true diner-style environment they have. Classic bar stools and a counter with several pies, cozy booths, and even outdoor seating! In the main dining area, the decor showcases all sorts of retro/vintage history with 8-tracks, vinyls, and license plates from decades past. As they are also along the Historic National Road, their menu reflects the other cities along the highway with their breakfast combos! If you want a different route to get here, they are also situated right along the White Lick Creek Trail, so it's an easy walk (or bike) across the pedestrian bridge to some delicious American food! As well as the ambiance I've discussed, I also love that they are a frequent participant of the Devour Indy promotions, as the promotions and deals they offer are well worth it! Over the many times I've been here, I've tried quite a few things off their menu, and they have a lot! Prices are very reasonable (I think they have gone up just a smidge since I've been there but nothing too crazy). If you stop in the morning (or any time, really) their cappuccino is AMAZING! I just get a basic cappuccino, but there are additional flavors you can add (Toffee and French Vanilla are two that I remember). Their burgers are always cooked to perfection, and the fries are a joy to eat (especially if you get the loaded fries!). Overall, this is a restaurant that is truly one of my all-time favorites and I will go out of my way to stop and have a meal here. read more

The oasis diner in Plainfield, Indiana is one of our favorite places to eat breakfast lunch or dinner. I usually tend to order breakfast whenever I'm there and it's always delicious. Their desserts and sandwiches are over the top. Their pies, although a little pricey, are always delicious. I often recommend friends to go there for their breaded tenderloin. It's one of the best I've ever had. The staff is friendly, the food, consistent, and I've never had a bad experience there. I highly recommend it. read more

Food is just ok. Chaim like metro is better which is sad to say. You think you're going into a New Jersey type diner but the only thing close to that is the aloofness of most of the staff. Theirs a lot of old memorabilia which you think will be cool but you quickly forget it when you sit down and everything is sticky and a little questionable cleanliness read more

Waitress cheered when a party of 8 left. I can't imagine the owner would be pleased. My burger was good. My guest had bfast and it was cold

Such a neat building! We stopped in on our way to go hiking and took our food on the patio. Our waitress was welcoming and personable. If you look closely it is possible to find a healthy item on the menu in the midst of all the fried items that they are more known for. Be sure to try out their root beer as it was delicious!! read more

Aside from the yummy food, I love the retro vibe. The staff is friendly, knowledgeable and attentive. Recommended.

Absolutely wonderful! My daughter and I went after a birthday party and both of us decided this was a "go back" spot! I had the special- smoked sausage, saurkraut, green beans, and mashed potatoes with gravy. Kiddo had chicken tenders, and we shared an appetizer sampler. Everything was delicious! I had zero complaints. We topped it off with a small ice cream, also yummy. I definitely missed food pics. We were starved! read more

I eat here often because it is within walking distance of my house. It has great food, a fun environment, a great location and preserves a little slice of Americana. Plus, the Hoosier State Sandwich - the breaded pork tenderloin - reaches its pinnacle of excellence here. All of their food is great, and at a decent price. Have a slice of locally made pie for dessert and you've got yourself a great day. read more

My son and I were out doing some winter clothes shopping and decided to grab lunch at Oasis Diner. We got a kick out of the atmosphere and the food was excellent.

We were too full for dessert but it looked tempting - next time! read more

Pretty darn good. We were looking for something easy but no fast food on our way out to buy plants. Stopped at Oasis diner. Ordered a burger and some chili plus raspberry tea. The tea was too sweet for me but by husband loved it. A personal thing not the restaurant's issue burger was good and fries were terrific. Chili was good as well. Server was delightful and friendly. Food took a while but place was busy so not too bad overall. Will definitely stop again when we are out that way read more

They make delicious fried pickles and onion rings. They got rid of their black bean burger for vegetarian people and their delicious sweet potato fries. That's a huge bummer for me as I loved those two and I am a vegetarian. They only have grilled cheese sandwich and tomato bisque for vegetarians outside of all the sides you get. The customer service was amazing! The ambience was just perfect for lunch. They have their own parking behind and to the side of the diner. read more

I met up with a friend for lunch here. It was a cold day with snow flakes blowing and rain predicted. Therefore I chose the grilled cheese and tomato basil soup. Both were warming and tasty. Since I'm in a diner a scoop of chocolate ice cream was necessary. Yummy for tummies! I would return read more

The service was great, our waiter was very kind & helpful. The food was okay, like a 5 or 6 out of 10. The fries were pretty good, but my Philly was meh. The atmosphere was very cool though. I'd go back just to get a milkshake and enjoy the music & decor. read more

Stopped here on my way back to Ohio. Came specifically for the pork tenderloin sandwich. It was huge! Fully 3 times the size of the bun. Had to cut it to make a sandwich that I could pick up. Tenderloin was delicious. Exactly what I was looking for. Fries are thin lightly breaded. They were yummy as well. I needed a nap after. Definitely recommend. Oasis is a cute old timey diner. Food was great and the service was impeccable. read more

Oasis Diner - Pork Tenderloin sandwich and fries! - Diners Near Me - Plainfield, Indiana

Went with family and we had the fried tenderloin, grilled cheese, double stacker cheeseburger, fries, onion rings, and a wedge salad. Everything was delicious. Probably one of the best pork tenderloins in the Indy metro area. Sodas are made there and cola and root beer were delicious. Onion rings and fries were great. Service was pretty fast, tho it took a minute to get seated. Decor is music and fun to look at. They also have a wide selection of delicious pie, but I was too full to get any this time. read more

Oasis is such a cool retro-diner experience. The tenderloin sliders were fantastic, and honestly one of my favorite tenderloins I've ever had. Our waitress was very friendly and super helpful in helping us select one of the Oasis-crafted sodas. The red cream soda was delicious, the butterscotch root beer was dessert forward, and we weren't too fond of the chocolate cola but it did taste like a tootsie roll if that's your thing! Will definitely come back :) read more

This diner has a lot of interesting history, most notably that this was literally moved from a different part of town. It was difficult to find what I liked on the menu as their selections were huge. I wasn't in the mood for a burger or anything like that, so I went with catfish and onion rings. To drink I had the butterscotch root beer, which tasted like heaven. By the way, they make their own sodas here. Very nice decor on the walls, including retro lunchboxes and records, cassettes and CDs were displayed on the wall! read more

Nothing short of incredible! It was my first time here and I will now have to come every time I fly into Indianapolis. If you're looking for classic midwestern diner food this is the spot.

Definitely one of the best stops I've had in Indiana read more

What an amazing little gem! Love everything about this place from the location and decor to the staff! They even had a pet friendly area for those well behaved dogs and thought that was great. Started off with a vat of coffee and it wasn't long before our orders came along. Substitutions were easy and allowed. Corned Beef Hash was truly shaved and shredded and not canned. What a plus. The biscuits & gravy with eggs and hash browns were cooked perfectly. All in all a great breakfast and if we ever come back to town it will be a repeat for us! read more
