My new favorite Mexican spot! I love that it's family owned and they've been in business for a while. The customer loyalty & how busy it gets proves they're definitely a town favorite. When you enter there's a seating area of booths to the left. If you continue further there's another little space of seats, a full L shaped bar, and more seating in the bar area as well as an outside patio with seating. I definitely recommend coming before dinner time. If you come for dinner be prepared to wait. If you want to eat here with a large party I recommend asking about a reservation otherwise I'd advise against due to how busy it gets! I'm not a fav of the chips & salsa as the salsa isn't flavorful or chunky enough to me. For those like myself who prefer spice & more flavor I recommend getting their salsa picante & mixing the 2, so much better! Their margaritas are good, I prefer the blood orange vest but they have a large selection of marg flavors and a full bar. For food I've had the nachos, tamales, enchiladas (I recommend the enchiladas de pollo verdes), tacos, and chimichanga. I got my parents hooked on the tamales! I love that they serve them as not a lot of Mexican restaurants do here & I love that they put meat both inside and on top of them. The establishment is always clean, the staff is always friendly & welcoming, and you can tell theirs homemade recipes coming out of the kitchen. I recommend ending your meal with the churros! Overall their price point, staff efficiency, and the consistency with the food makes this the best Mexican restaurant I've had in the area which is why I keep coming back & would bring guests here. read more

This is a neighborhood Mexican restaurant where customers become friends. It says a lot about a place when there are so many regulars and everyone seemed pretty happy with their meal. They have a big parking lot and it was still rather busy on this Tuesday evening of my visit. It's a casual atmosphere and there were plenty of open seats when I visited. We decided to sit at the bar and we were immediately greeted and offered chips & salsa and they were ready for our drink order. I chose the fresh squeezed Cadillac margarita. It was very good and refreshing. We were brought chips and salsa that were better than average. My dining companion ordered other kinds of salsa that were quite spicy, and I liked it mixed with the regular salsa. I ordered the cheese tamale plate that came with three large cheese tamales, fluffy rice, a small lettuce and tomato mound, and vegetarian pinto beans that were quite tasty. The highlight of this visit was the staff. Five stars! They know how to treat customers well. read more

I recently used El Tio Pepe for our catering needs. They were so easy to work with, reasonably priced and best of all - the food was absolutely amazing! Everyone raved about the taste! I will for sure come to El Tio Pepe to dine in soon and also use them for our catering needs. read more

Amy was great our server! the drinks was strong n many variations of drinks. Price for food was a bit high for basic Mexican. Loved the decor especially the star lights. Cool seeing them play guitar for your birthday made them unique for sure. Bar inside and plenty of TVs going. Bigger than it looks for seating. read more

First time I was not pleased with a meal at El Tio Pepe in O'Fallon, Mo. I shad lunch at El Tio Pepe on 4/23/26. I ordered a lunch special of 2 items plus beans and rice. The lunch was not warm and the yellow cheese was cold and looked like plastic on my burrito and taco. I doubt it if it was real cheese. The chunk beef was over cooked and dry. The chicken on my taco was very cold. I told my waitress and she said she could put it in the microwave, but would have to charge me for queso. My wife's meal, Pollo Loco, was cold as well as my son's Tamale plate. Very disappointed in our server ( table 53 at 1:05) and the quality of the meal. read more

Great service with great food. Holiday time and staff was wonderful. Got every request right.

A great place for Mexican food!!! The staff is really good and the food is delicious. My only complaint would be there's not much of a waiting area and the parking lot is big but OFTEN gets full - literally where you'll be driving in circles looking for someone to leave. Of course, this is cause it's such a great place to eat. read more

The meal was very good as well as the margaritas. I got the pollo Cancun which was fantastic. Had sautéed mushrooms, shrimp with rice and beans. Very delicious overall. The margaritas were also good and had the right amount of sweetness to alcohol ratio. The service was slower but it was busy per usual. It is a very loud atmosphere but the decorations make for a nice ambiance. I will return. read more

Food was subpar! Spanish rice tasted very old. Service was poor. My husband had the combination platter and I had the beef chimichanga either of which tasted like there was any fresh ingredients, tasted like it had just been microwaved and sent out .This place use to be our go to place for mexican food, but no more. Very disappointed. read more

First, I want to say this is one of my go to places. It's a favorite and close to home so I eat here a lot. Usually twice a week. The food here is consistently wonderful. Always authentic and it's family owned with its third generation just starting there. The service is great, we know the workers by name and they remember us and usually our orders. LOL The restaurant has been recently renovated, it has an outdoor patio and garage doors that are open when the weather is nice. If you are looking for good food, good people and a clean bright atmosphere, this is your place. I'll add new pictures soon. Hope you give this restaurant a try, you won't be sorry. read more

Awesome place! Always busy too. Great authentic Mexican spot- portions are large and service is fast. Margaritas are great! Queso fundido dip is delicious- this isn't the soft cheese dip though FYI- harder cheese dip with chorizo. More than enough for 2-4 people. The fajitas are always delicious. Fresh and hot! Salsa and chips are fresh and amazing. Highly recommend! read more

What a great restaurant! When we pulled up we thought we would have to wait because the parking lot was poppin! We went inside and they ended up seating us right away! You chips and salsa - obviously - and we started off with a frozen mango margarita & a house margarita on the rocks. The drinks were great and came out quick! We ordered our meals & I got 3 chicken tamales and my boyfriend got the pollo loco bowl. Both were delicious and were big portions. We each took part of our meal home. I would give this place a 5/5 and would def come back! read more

WOW! Totally impressed! Sometimes when we travel we have to get food to go as we have a pet with us. So we ordered food for pick up here - first the parking lot flowath over which usually is a sign you are about to have a great food experience! And that we did...plus the fact it was to go which you know adds a difficult element to deliver a 5 star review which they surely earned tonight! We ordered their Flautas, chimichanga, enchilada rancheros, & fajita quesadilla. Flautas had the perfect crunch and flavor with refried beans that were so smooth they melted on your tongue with flavor! The enchiladas rancheros were delicious although not what my husband was hoping for (he loves the pepper/onion w/ carnitas version) however they delivered a great punch of flavor. The chimichanga with shredded chicken was crunchy, moist, cheesy and just THE BEST evah! Lastly the fajita quesadilla was just beyond words! The flavors were so succulent - could eat that everyday (just wouldn't be good for the waistline lol)! This place has been bookmarked for sure! One day we will be back ....in the meantime you all make sure to try this place!l and keep it hopping like it already is so it's here next time we are driving by! Sorry no pics - hopefully this write up is enough to tell you - AN ABSOLUTE MUST TRY! read more

OUTSTANDING!!! A Mexican restaurant that had a dish I'd never heard of... Who'da thought? Stir fried cactus??? YES! And SO tasty with chorizo and eggs. A definite win as far as I'm concerned. The flavored tequila made for a GREAT Margarita. I want to come back and try their tamales! They're usually my go-to order at Mexican restaurants, and a regular at the bar raved about theirs. Service was pretty good, especially since they were PACKED! Prices were reasonable too. ALL GOOD! read more

Each time we've visited El Tio Pepe over many years we have experienced a welcoming atmosphere, great service, and outstandingly delicious food. They expanded their square footage a few years ago so the restaurant can better accommodate their many guests. Though my wife and I have many favorite dishes, we would encourage you NOT to miss their "Quesa Pepe!!" The chihuahua cheese is chewy and mouthwatering!! We suggest giving El Tio Pepe a try, you might just find you like it. read more

We've been wanting to stop in and try the place out and we were glad we did! We were greeted quickly, sat and had chips n salsa in the same breath. Server came quickly, took drink orders and came back quick and got food orders. Food was EXCELLENT! I had the verdes enchiladas with pork. The wife had the Chicken Fajitas. We will be back! read more

Kinda shocked to find decent Mexican food this side of the river (IYKYK). I've been driving past this place for years and we finally decided to stop in for a visit. I have a few criteria I use to judge a Mexican restaurant. The first one is the chips and salsa. Any connoisseur knows not all chips and salsa are created equal. The chips are thin with enough thickness to handle the salsa without breaking in the salsa bowl, or worse on the way to your mouth! The salsa had a warm heat and a medium texture thin with a little chunk to it. The second measure is the margarita test. Again any connoisseur knows not all margs are created equal. I went with the standard house margarita with Grand Marnier. The flavor was spot on and the combination of mixer to alcohol was perfect. Definitely felt like a solid cocktail without being watered down or cloyingly sweet. The last measure is by the tacos Al pastor. They aren't called this on the menu, but a trained eye knows what to look for. This dish can easily get dried out, made too spicy, or lack flavor. None of that could be said about this dish. The beans and rice are your standard fare. The restaurant is clean with a buzzing atmosphere. The staff are personable but not overly doting. I'd recommend them over all the places in comparison to all the other places in St. Charles County. read more

Service, Cleanliness, Food, and Margaritas are great. It gets crowded. Don't forget to grab a loaf of sweet bread.

Food was delicious! Service was good. Super busy though so there was a bit of a wait, but it went by quick!

They are amazing. They always deliver great food with great staff. My new favorite Mexican restaurant.

Also, the chef said he put "the mexican seasoning on it" when I provided feedback about the blandness ...

If you are in the mood for some great Mexican food, this is the place. This is about our third time here and it has been a great experience each time. It's usually crowded but they do a great job getting you seated pretty quickly. The atmosphere is lively. Our server tonight was exceptional. Super friendly and attentive. The food of course was delicious as always and the margarita was top notch. Highly recommended!! read more

Good service. Good food. Good environment. Friendly staff. The only downside, need more parking.
