No, it's inside the main pyramid, in the place to the right (as the entry is at your back) that used to be a jewelry store.
The menu is tequila, tequila and more tequila. The margaritas are SUBSTANTIAL and vary with any number of different ingredients. We tried a blood orange margarita and it was divine.
There is a limited menu of some light fare too, we tried something with cheese and guava and agave.
It's the perfect place for a relaxing stop on the tour of the world showcase. :D (Of course if you start with Mexico... lol. We start with France or Canada depending upon how we enter).
WELL worth the visit. The new place wasn't quite up and ready yet when we were there last Friday. It's getting closer, but not done yet.
