Are you thinking of Paradiso 37? It's going in Downtown Disney/ Pleasure Island and will include "a one of a kind tequila tower bar with more than 50 kinds of tequila and a selection of signature frozen margaritas." Sounds great to me! I've seen reports of the opening date being in early May, Spring, or Summer, so it's hard to say when it will finally open.
I remember reading about the tequila bar that was supposed to open in Epcot also...it was a year or so ago but nothing ever came about it....I guess they decided to open it up in downtown disney
I think it's safe to say after two years of rumors about this tequila bar it's never going to happen. Too bad because it would have been a great addition to the Mexico pavilion.
