Excellent food and great atmosphere. Carne Asada was fantastic. Horchata drink came in a HUGE glass (sometimes places skimp and use a small glass). Will definitely come back here in a heartbeat. read more

Came back to check out theor new updated patio. Unfortunately they were busy. I guess everyon3 had the same idea. They added a side patio that's half exposed to the outside. We ended up sitting at a high top near the bar. Which no complaints. Husband was able to watch some of the soccer games. Our service was good. She essentially on top of making sure we were doing good. Staff would check in to see how things were. I had the black windows margarita. ( one of my faves I had before) but instead of my usual food. ( which i bounce between enchiladas or fajitas) i went with their burrito colorado. Husband tried their house burrito. He's normally a chimichanga guy. I enjoyed mine. It has options of steak, chicken, or shrimp, topped with cheese sauce, picó, rice and beans. We enjoy their chips and salsa. Hopefully in the future we can sit outside on a mice day. They do carry soft serve margaritas but I didnt try yet... read more

Absolute racket. Not only is EVERYTHING expensive but $3.50 for a some sour cream on the side $1.50 for some hot sauce on the side $3.50 for extra tortillas (never got them) The $30 tower or margaritas (88oz) was completely filled with ice. Not even half of it was margarita. Floored. read more

Love a classic Mexican spot. The chips and salsa and queso dip were delish and my husbands burrito was HUGE. Reasonably priced margs and beers. Plenty of parking and the restaurant is decently big so no wait time for a Saturday night! read more

I went to La Casa Mexicana for a Grand Margarita to celebrate National Margarita Day. The place was packed! There was a delay for placing an order, but they were super busy. The staff were apologetic and nice. I ordered the Fajitas Gorda that contained a little bit of everything. Steak, chicken, shrimp, chorizo, bacon, carnitas and monterey jack cheese. It was fantastic. The food made up for the wait! read more

Wanted something quick and tasty for lunch today so we decided on La Casa. Lunch crowd was in full swing but we were in and out in no time at all. Service was splendid, she was nothing short of amazing. The Veracruz plate was light and delicious, very fresh and filling for a lunch option. The birria torta was sooo good! Hot, full of flavor, and pretty big. read more

Their new patio is simply amazing! Very cool vibe. Been there 3 times in the past couple of months or so. Service is very friendly, and the food is great! Inside is always inviting, but can't wait for nicer weather to enjoy their patio again. Highly recommend this place! read more

It was okay... my rice and beans (I wasn't super hungry) was the last thing to come out at our big table of 10. The waiter hardly ever came by so I was without a drink refill several times throughout the 2hrs we were there. Plus, their pricing is way too expensive. My Dr. Pepper was $4.50!!! That was as much as the cheese dip I ordered. Altogether the food was fine but I can't afford to pay as much for the drink as for the food. So I probably won't be going back until I see their prices match closer to just as good Mexican food elsewhere. read more

Service was Amazing from Liz! The food was Awesome! The Ambiance was festive! LaCasa Mexicans is #1 in my opinion! The Management is Awesome too!! read more

Their customer service is very good, bring out all the ordered food items all to together, not one by one.. gracious...⁉

Have been going to La Casa on and off for many years due to its proximity to my home. It has always been the fall back to good Mexican food in the area as they continue to disappoint. I'm giving two stars because the service is usually very good and was tonight as well but the food quality has been only good and now poor. There are several other local Mexican places that deserve my money and will get it from now on. The new patio looks great but bad food in nice patio is still bad food! read more

Everything was so very good. The chips, salsa. My husband had 4 enchiladas, he said they were amazing. I had a shrimp scallop dish over the most delicious rice I have ever tasted. The shrimp And scallops were cooked perfectly. Even though it was crowded, the service was exceptional. Food came out quickly and was very hot. read more

Chips and dip served right as we were seated. Silverware was dirty so we asked for a new set and that was dirty too. The drinks are huge! Definitely sharing size, tasty but not sure they even had alcohol in them. I ordered the Quesa Birra and my fiancé ordered the Lobster Tacos. Food was just okay. Service was a bit slow. We asked for extra napkins and he didn't come back. Waiter never really check back in after the food arrived. read more

Best place in town, great wait staff, great food! Tacos Al Pastor are amazing! Jalapeños Margarita is so good, so is the California burrito.

Decided to try something new for our Anniversary. Big mistake. Got seated right away, drinks, salsa and chips started good. Ordered our meal, came out fairly quick. Server dropped plates and ran away. Portions were small and food was cold. Had to eventually go find hot sauce on our own. No drink refills. There were servers all over the place but literally looked at you and kept going when trying to get assistance. Finally brought the check and ran away. Paying the bill, never was asked how our meal was or if everything was good. Don't waste your time going here. Plenty of other restaurants with better service and portions. We won't go back. read more

forget happy hour margaritas! no alcohol in them. what a joke! service practically non existent!

Normally the food is ok and the service is good, however, not this time. While I love to try and hear Spanish, the waiter was spending so much time trying to be cute he totally messed up our orders. He then barely returned to check on anything until we were basically done...then took forever to get us our check. It was a very disappointing visit and will ensure it will be long time before we return to this location...maybe the one in Edwardsville will get it right. read more

This has become our go-to Mexican restaurant. The entrees are excellent and the salsa is amazing. Last time, I had the fajita burrito. It was as long as the plate and amazing. The steak was excellent and it had a terrific sauce on it. The rice and beans were good too. We also ordered queso with the chips. It was good. I took off a star because the chips aren't the best. They're relatively thick. And, I honestly don't know if they're homemade or not. I would say they're a bit below average versus the typical thin, crispy tortilla chips you find at a local Mexican restaurant. The place has a lot of drink specials too. And, I like that the menu is a blend of old favorites and new twists, like street tacos. Price is what you would expect - about $10-$15 per person for dinner. We will definitely be back. read more

This is a covid Era review. Came in around 8pm on a Sunday, sat outside as Illinois requires it. Overall service was pretty lackluster, there was a lot of waiting for drinks, ordering food and then trying to get the check and waiting for him to come over and grab the credit card. The reason for the 4 stars is because the food is pretty good and honestly I had the burrito off the a La carte menu and that $5.25 burrito was enough to fill me up. Some other members of the table did receive full meals and they were humongous. Also, the chips and salsa were pretty good! read more

Best Mexican food in the area! The Chorizo Queso Dip is a must have. Try the fajitas, the tacos, and the sangria margaritas. Staff is great too! read more

We used to love coming here. But the last three visits have showed that they just don't have it anymore. Went for lunch with my son and service sucked. The server was hardly around, asked me less than 20 seconds after our plates were delivered if we needed anything. At that time I hadn't even had a chance to check everything over. That's when our server just disappeared. I waited for over 10 minutes to ask for limes and drink refills and finally had to find a manager and asked for another server. The manager brought the server to my table and she was so rude and replied " I asked you if you needed anything!!". This was about 15 minutes after we had gotten our food that she was brought back to our table. She was incredibly rude and ruined the whole meal experience. I'm not sure when or IF we will be back. Food prices are outrageous right now and it's not worth paying that much to have such terrible service. Also the fact that they now charge a fee for using a credit card is dumb and greedy too. read more

My family and I love La Casa Mexicana! It is by far the best Mexican restaurant in the area! I love their beef enchiladas and tacos! The meat is cooked to perfection! My wife loves their chimichangas! She says they are the best! I highly recommend the sweet corn. It is the perfect side dish. My children are very picky eaters so I would like to say thank you for offering choices for them. They enjoy the chicken tenders and Mac and cheese. read more

We arrived at 6:27pm, got seated right away, had our drink orders taken at 6:30pm, food orders taken at 6:35pm, and our food was brought out ~sizzling~ by 6:45pm. My fiance and I were both astounded by the speed of the staff! Our waiter was very friendly and attentive. He checked on us multiple times after we had our food and drinks. We personally didn't love the taste of the chips. I'm thinking it might have just been a bad batch because I've never had any issues before. However, we opted for the cheese dip this time, and this might have been some of the best I've had. They knocked it out of the park. For our entrees, we settled on the Create Your Own Combo and picked three items to try (burrito, tamale, and tostito). We thought that this was the perfect amount of food to split between the two of us. Each item was delicious! read more

One star because there's no stars for zero. I've been here before and forgot to rate it last time. So my complaint is they charge an extra 2.5% to use everyday currency like a credit card. I'm quite aware of the charges that credit card companies charge to use their services but to charge me more than everyone else is called discrimination in the eyes of the government and if more people would object by not patronizing them we can push these kind of businesses out of business. If they want to cover their surcharges then raise their prices across the board. It's just the cost of business but to discriminate against some people is not the way to run it. Never coming back at any of their establishments. read more

Our go to place in OFallon, IL for Mexican. I come from AZ and am half Mexican, so I can get a little particular. However, we love this place because the food is delicious (definitely recommend street tacos arrachera and pollo poblano). I'll admit, this is still a classic American Mexican dinner place, not the most authentic Mexican you can find. However, as I mentioned, this is our go to place in OFallon, IL. Service is always kind and quick and ambiance is great. Fits the bill for a Mexican night out! read more

The food and service is always good at this location. A great go-to place when you're in the mood for Mexican food.
