I'm not so sure about La Cava del Tequila for a virgin margarita. I don't think they use sour mix there, so a margarita without the tequila and orange liqueur would basically be lime juice on the rocks.
Thanks both. I agree on the bar inside the pyramid. I have gotten the jalapeño margaritas there (which are excellent) and it is all made fresh and no mix. My kids like margarita mix but obviously cannot have a real one. I was hoping for maybe something for them. I know they make the frozen ones outside was not sure if maybe they had non alcoholic ones. If not they will understand though so not the end of the world.
