We had a great experience at Rosalita's Cantina. The margaritas were excellent and definitely one of the highlights of the visit. The chips and salsa were really good, and the guacamole was outstanding -- fresh, flavorful, and easily one of the best parts of the meal. The food overall was solid. Personally, I thought the tortillas were a little sweeter than my preference, but my wife absolutely loved them, so that really comes down to taste. The atmosphere was fun, service was friendly, and we'll definitely be back for the margaritas and guacamole alone. Great spot for a casual night out. read more

The food was fantastic and on time! The service was outstanding, the staff were personable and eager. The ambiance was electric, the number of people that were in attendance was in the hundreds. It was as if they were giving away gold! read more

This is a beautiful building and new to the area. When we arrive, we were told a 30 minute wait but we did not have to wait 30 minutes before getting seated. The restaurant is very large. They took us to a booth. It's pretty close with kind of private and very nice. We arrived with plenty of time with happy hour left over, but since it took them so long to see us, they would not honor it, which was frustrating Sophia R was our server and she messed up our tickets. For example I had ordered the guacamole and there were five of us and she split it between three checks which doesn't make sense and it was just something that I had ordered for myself. We also had ordered a margarita pitcher with no ice and she brought us a pitcher full of ice hardly any margarita. So we had to order another and yet again they brought it filled to the brim with ice. Even the receipt said no ice. Very slow service. We thought we had our order ready and then it ended up. They brought us the wrong order. They took it back. Hopefully it made it to the right table. We had to ask for things multiple times like and our waters. I know they are a newer restaurant so hopefully things only improved from here read more

We had my five gfs for girls night out. Drinks n food. Now I'm per person is about 20$-40$ tab depends the meal or drinking. My bill was 100$ for two meals n two drinks. She charged me for guacamole my friend ate n charged everyone for. Mango margarita was good. Bit of a wait n server said kitchen was a mess. Cute decor and how nice they set up the place it doesn't look like a low grade Mexican spot u know. Tons of seating but not enough parking spots so be prepared. read more

What a great place and we decided it was our new favorite place! Forgot to take pictures because we were hungry. lol read more

Price is a little high but the ambiance is perfect and nice looking. Child and salsa rock. Service was amazing too

We ate at Rosalita's today. The service was very good, the food was tasty, and the decor was beautiful. We will be returning when the patio is complete. I had the birria tacos and my husband had the chicken cauliflower rice bowl. read more

Rosalita’s Cantina - Mexican Near Me - O'Fallon, Missouri

My wife and I went on a Friday night and expected a long wait. They told us 50 minutes but we were seated early. That was expected with the crowd. The chips and salsa and we highly recommend the queso cheese dip. It was fantastic. I had the fajitas and Sue had the chimichanga and both were excellent. We've been to several different Mexican restaurants in the area and I think they're all gonna lose business due to this new restaurant. Our server Keaton did a great job and we tipped him well. We will be back! read more

It's midweek and thinking it wouldn't be busy, my husband and I decided to give this place a whirl. I should've stayed home and had cheese and crackers. The restaurant is beautiful but the music needs to be toned down just a bit, I couldn't hear myself think and the exterior is still under construction. The ambiance was pleasant, however, the hostesses need to be covered up just a little bit. Perhaps something a little more like black slacks/skirts-shorts that are more. The waitress we had was already in the weeds when we were seated at our booth, which by the way was huge, especially for 2 people. The menu was "eh", not really Tex-Mex just basic. We had uber oily tortillas and salsa complimentary and I went ahead and ordered a side of guacamole. I was disappointed because not only was it not cold, but starting to get that crusty hue of brown. We ordered fajitas to share and that was the beginning of the end. In most Mexican or Tex/Mex restaurants everything comes out at once, the sizzling fajitas, the tortillas and the sides. We received the sides first, and it was already lukewarm. By the time the fajitas arrived the sides were dead cold and the fajitas were not all that either, no sizzle, more like fizzle. The chicken was tender but it was all onions and green peppers, really colorless. We're used to seeing red, yellow, and green peppers. The sides were really lacking in freshness and presentation. It looked like it sat under the lamp for over 10 minutes. The sour cream was melted, the guacamole was completely brown and the beans were runny/crusty if that makes any sense. The manager did come by the table and expressed her apologies on the quality of the food and offered a 15% discount, but still it was just not what all the hype it was made up to be. We personally will not be coming back. This place has a LOT to improve. read more

They have uncomfortable seating. Long couch against the wall. My guests I brought there all seniors , sat to high. My sister's food was served cold. Wr order chicken fraitias with shrimp and they charged (without asking us) shredded chicken that we got charged $4.00 extra for and none of them like shredded chicken. I realize they are still adjusting but there are alot of good mexican restaurants in O'Fallon. Ambiance was beautiful seating not so great. read more

The food does not compare to the other chain and I have no idea why.. I had very slow service and a server with a strong attitude about us needing a different table since it was for 5 not 4. Not very good to start this new location up. read more

Food, cocktails, service and ambiance is worth checking it out for yourself. Thoroughly enjoyed all of the above. Christy our server was amazing! read more

Waited over an hour for food, had to go to the bar and get our own drinks. When the food eventually arrived it was cold. Our waitress kept apologizing and started to cry. This is a new restaurant but still no excuse. Maybe we'll try again in 6 months when they have their act together. read more

Cool location. Margarita and food sub par to bad. Best part of meal was chips and salsa.

Everything was very good, especially the food, service was a bit slow but understandable considering how big the place is. We will be back

If you have littles and need a changing table.. DO NOT GO. There are men's, women's, and unisex single toilet bathrooms and NONE of them have a changing table. We will not be back for that simple factor. There were at least 15 babies in the restaurant when we went and I truly couldn't believe they didn't have not even 1 single changing table. On top of that we put our name on the list, got called our table was ready, and when we got inside they took our name off. Once we got sat several minutes later we didn't have anyone come to the table for 15 minutes and my husband tried to ask 3 different employees and was ignored by all 3 walking past. He finally was able to get maybe a manager walking around with a tablet and then she sent someone over. Not the servers fault for not being assigned the table. Food was honestly just not good, had to send back my husband's, and the kids meal honestly my son could barely bite into the chicken tender. You also cannot get tortillas on the side for any meal??? literally not even for fajitas..??? We spent so much money for getting 2 sodas, a kids water, a queso dip, 2 regular meals, and a kids meal. We were excited and it was a horrible first impression. The restaurant is beautiful and I'm sure the patio will be too, but not enough to get us to come back. (Not when I can buy the chips, salsa, guac, queso, etc. at dierbergs since those were the only things we would want to eat again). read more

We came in at 2:30 in the afternoon and it was not busy. We were seated and no one stopped by our table for over 18 minutes. No one stopped by to ask for our drinks, drop off chips, get our order or to just stop by and introduce themselves as our server. While we were seated I saw about 3 servers look over at us but no one made their way to check on us. We decided to leave and go elsewhere. I understand this place literally just opened. I'm hoping it's just a small hiccup as they get their legs under them. Just really sucks because I absolutely love Rosalita's in Des Peres and have been waiting for this one to open for months. read more
