    Was crushing the streets and found Mario's Cafe. Located on Main Street in O Fallon, Mario's is a fresh spot to enjoy breakfast or lunch. We stopped by on a Sunday morning and saw a very busy cafe. We were seated without any issues and was welcomed by Mario the owner and our server. Very friendly staff and provided the specials for the day. Mario's has both traditional breakfast options as well as a Hispanic options. We went with Mexican breakfast and was impressed with the authenticity of the dishes. Prices were reasonable and service was great. I do recommend trying the Mexican breakfast options as there aren't many restaurants serving Latin cuisine in the mornings. Highly recommend and will be back!!

    Great small business. Visited for breakfast. Service with a smile. It's a quaint space so not ideal for extremely large group. Breakfast tacos were amazing.

    Breakfast food was good. The hash browns had a seasoning in them you would expect on fries which tasted good. I would go back.

    Excellent food, service and drinks. Open ALL day so you can enjoy breakfast, lunch or dinner. Menu has many options. Outdoor patio is an added plus!

    We brought our own Mario to Mario's in O'Fallon!

    Fantastic authentic Mexican restaurant. Do not hesitate to go. But be careful to order the jalapeños, cause they bring the heat at Mario's!

    My new favorite Mexican spot! I love that it's family owned and they've been in business for a…read morewhile. 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.

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.
