I've been to this restaurant several times and have yet to be disappointed. The food here is more of the upscale Mexican variety and not the typical Tex-Mex fare. Be sure to try the grilled quail or camarones al agave.
They have one the best margaritas I've tasted. If tequila is your drink of choice, then you will be pleased with the numerous selections available. Make sure you ask about cost of the tequila is before ordering though, as some can be quite expensive. Try the tequila sampler, which consists of your choice of four tequilas and a sangrita chaser for a modest price.
The one drawback is the service here is sometimes lacking,especially when it is busy, but other than that it is an overall enjoyable experience.
