It's mid-priced Mexican cuisine on the fast. Think of it as the next step up from Taco Bell, but a step down from Pedro's or Chi-Chi's.
Not everything on the menu is a winner, but the pulled pork quesadillas are outstanding and the Mexican gumbo is pretty solid, especially on a really cold day.
I rarely understand the people behind the counter on the first try. Usually, they have to ask their question two or three times. I love our Mexican brethren, but they're not too fluent on zee Engrish...
Don't think this place is the be-all, end-all, but it's okay.
