Definitely upscale compared to a lot of "Mexican" restaurants in Atlanta, the food here is very good and portions are huge. They make their flour tortillas in-house, the beans that come as a side are awesome and margarita fans won't be disappointed. I don't really understand why they need valet parking (a pet peeve of mine, I admit), but the parking lot is shared with Ted's Montana Grill next door, so it can get pretty close to full. Pricing is mid-level, but not out of line considering the quality and quantity of the food. I think they do seafood especially well, but all the set platters are worth a try. During nice weather, it's nice to sit on the terrace - noise from Peachtree Street traffic is surprisingly unobtrusive.
