I'm hoping to check out a few places for the rehearsal dinner during my Vegas trip. We'd like a place with a private room, not a buffet, not super duper fancy, but still nice and fun. I was thinking Dos Caminos (prickly pear margaritas, giant bowls of guacamole- heck, yes), but I don't remember seeing a private room though I think the website said they had one. Suggestions? Opinions?
