Review: I can't echo the sentiment of other reviews (particularly on Yelp) about the zoo-like atmosphere and terrible service. We went late Sunday night and the place was almost empty. Most of the food is half off from 10pm to 12am which is a great incentive to eat there late. As far as I can tell, the vegan sour cream is not Tofutti or a commercial brand; it says "tofu sour cream" in the menu and definitely has a different consistency and taste from the processed, soy-based stuff most vegans are used to. Not bad, just different. The soy cheese is most likely Follow Your Heart though I couldn't find out for sure. The vegan options are incredible. They have a crispy tofu dish that rivals any Asian restaurant in Columbus or otherwise, complete with a mild peanut sauce, sesame seeds, and soy sauce. It was incredible. They also feature hummus with Mexican pumpkin seeds which sounds incredible, though I didn't try it. The burritos are excellent and many other dishes can be vegan, including the tacos. The wealth of menu options and customizations make Mad Mex a great place to go with your omnivore friends. They are a relatively small chain (about 10 stores nationwide), so recommend they carry a popular food service mock meat (Boca, for instance) before they blow up! We told our server and he was very receptive. Overall - another excellent restaurant in Columbus for vegans and vegetarians, with late-night hours.
