Had an Entertainment book coupon for this place, so decided to give it a shot. Really, no ambiance here, its pretty much a hole-in-the-wall, but this is the most authentic Mexican food I've had since....well, since Mexico. Cheap prices and big portions, gotta love it. Mostly frequented by the spanish-speaking population, Tom and I did feel out of place for a few minutes, but got over it quickly when we got our lunch--we tried their tacos, burritos and quesadillas--all excellent. If you want Mexican food that is not Americanized, give this place a shot.
