We recently dined at Las Margaritas and had another fantastic time with great service. Our group sat in the bar area and we were able to watch a soccer game and a Cardinals game at the same time. I ordered a chicken fajita quesadilla plus a margarita and both were absolutely delicious. Our waitress Sassy was awesome!
