This res't was highly recommended by the hotel staff, but my friend and I weren't totally impressed. Great ambience and really good food is slightly outweighed by the difficulty in finding the place. Another bad note was that, sadly, the margaritas were very poor -- especially considering we paid extra for Herradura Silver in mine and Patron in hers, but could barely taste it. We might have gone on a bad night, but I would recommend holding back your excitement til you're there and decide for yourself.
Pros: Ambience, tapas
Cons: Location, weak margaritas
