On the upside, the food is authentic and pretty cheap. $7.95 for a chile relleno, an enchilada, and rice and beans? Sign me up. It's way better than Cuzamil on Murray Ave charging $14 for two chiles rellenos. It has the typical cheesy music / futbol on TV kind of atmosphere.
The service is pretty crappy though. Our waiter took our drink orders and told us chips & salsa would be on our table in a moment. Five minutes later, he came by and asked "Did I take your drink orders already?" Food arrived in a decent amount of time, but soda refills never did. I agree with Juan C about the chiles rellenos being pretty lame - the pepper was thin and pretty wimpy, and the seeds looked really dried out and old. Once we were done with our food, our waiter cleared our plates, then got into a lengthy personal discussion with another customer while we waited for the check.
Overall: decent food for the price, but if you live in the city it's not worth the drive.
