great post about Cava del Tequila - I think the best part about that place is all the different tequilas and learning about them and trying them, etc. ... oh, and the margarita's aren't bad either
Our last trip we did bring our daughter in there with us (she was 8mo. old at the time), so I don't think the concept of brining kids there is crazy - but we knew what it was and didn't expect them to have stuff for kids there.
oh, and they do let you get stuff/drinks to go so that is always a great option if you have kids but want a great tasting margarita
