My wife and I are taking our 3rd Food and Wine Festival trip this October. We are going for 3 days but only going to the festival for one full day. We both want to try some tequila at the new tequila bar in the Mexico pavilion however are not sure we want to spend an hour learning the history of same. Does anyone know whether you can simply walk into the the new tequila bar and order a tequila or do you have to register for the event?
