There are about three different Mexican restarants to choose from in Tullahoma Tn. however in my honest oppion Casa Mexico is absolutely the best. I always recieve fast service from the time I walk in the door untill I pay my bill ( which is fairly priced by the way) They offer a wide variety of choices my favorite is the.. Nachos al Carbon.. it's a fairly simple plate of tortilla chips, refried beans, chicken and mexican cheese dip. They have mouth watering Fajitas as well and all of their meals arrive no longer than 10 minutes after they have been ordered. You have your choices between afew but since they moved to town I have not seen inside the rest of them. They make the best margaritas as well, just don't tell my boss that he'd ask why ours isnt the best.
