The Arroz con pollo (chickencheese and rice) is very good. I usually eat it with the chips like nachos. The sweet tea is the best in Cookeville in my opinion.
Roasted jalapeños are awesome. Have homemade salsas too! Chimichangas are great. Wouldn't get the steak again. Stick to ground beef. Chicken is alright.
One of the best Mexican places in town. Most popular, and fast service. Easily get in and out for your lunch break with time to spare if you get an hour.
