I'm going to a work conference in San Antonio, staying at the Hotel Valencia on the Riverwalk, and have two free nights. Where should I go for dinner? I won't have a car, so somewhere around the hotel or on the streetcar route would be preferable. I'm open to any kind of cuisine, and pretty much any price range (from hole in the wall to expense account type places), so long as the food is amazing. Thanks for any recommendations you may have!
