Las Margaritas

"Hecho En Mexico"

About Us

We’re Las Margaritas, and we’ve been a Mexican restaurant here in O'Fallon, MO, since 2015. We believe in serving large portions of the best-made food to fill your soul and offering margaritas, fajitas, burritos, and more. We started this business as a way to honor authentic Mexican cuisine and as a way to spread the love and joy of cooking. We’re looking forward to growing our business to continue to serve and partnering with Wentzville, Lake St. Louis, St. Peters, and the surrounding areas' consumers to continue to add exciting new items to our menu. We’d like to personally invite you to stop by and try our fresh-made guacamole for yourself.

Was pretty good, my car battery died in the parking lot and the staff gave me a jump, friendly service. 10/10

On 1/21/2025 Kummy K. had this to say:
I spoke with server about eating something to help warm me up. It was a cold day, 10F so she recommended the "pozole". Absolutely delicious, I added all the helpings. Could not finish it but left with a full stomach. Great place to stop by and grab a bit. Staff is helpful, the place is clean, and food is delicious.

On 1/3/2025 Blake S. had this to say:
Las margs is always a good time with good food. The trio special is the best menu item in my opinion and I have eaten quite a few different things here. Service is always quick/kind and the environment is usually fun. I will be returning many times again.
