My husband and I will be in Las Vegas May 29-31, staying at the Bellagio. We will have a car for one day, and I've made reservations for lunch at Rosemary's, but the things I'm reading lately make me wonder if it makes sense to cancel and go to Lotus of Siam instead. (If they're both worth it, we could of course take a cab on another day.) Also, I'd love recommendations in the Bellagio and neighboring casinos. Right now we've got reservations at Picasso and Olives. Are there better choices?
