Nope-not authentic, pre-prepared, the chips are way too greasy and flavorless, and every entree tastes the same as every other entree. I went there with a party of five.l tasted everyone's entree. Tasted like we were all eating the same thing.\nI have not had authentic Mexican anywhere in Madison. I'm told by my friend from Mexico, that yellow cheese is not used in Mexican food, nor are black olives.
