The Canyon Ranch Cafe is a really relaxing way to start your day - or to recover from a hangover! It's also a nice change from say, going to the Grand Lux, where it seems everything comes in huge portions.
Absolutely agree with Jennifer H that this is one of the few quiet places in the hotel. Just sit at the counter, have one of their great omelettes with a coffee, grab one of their newspapers, and chat with their always friendly staff.
Great tasting food, reasonable, healthy, portions. Go workout at the SpaClub, then after breakfast, walk out to the 4th floor pools at the Venetian. Your day doesn't get any better than that :-)
