The charming Mexican murals and marvelous margaritas may attract some of the patrons here, but it is the food that will bring them back. Sure, this place has the obligatory burritos, chips and guacamole; but it also has applauded appetizers, unusual entrees and delectable desserts. Chef Sue Torres is innovative more than she is a stickler for authenticity and has come up with many dishes which, if they do not have them yet in Monterrey, Mexico, then perhaps they should.
