We've been fans of Bellagio for more than a year now. Menu favorites include the roasted red pepper hummus (don't let the jalapenos scare you off -- it's really not very spicy), the Greek salad (crispy, fresh Romaine; amazing dressing), the classic gyro, the chicken shawarma pita (big pieces of perfectly cooked white-meat chicken) and the thin-crust pizza. We have several vegetarians in the family and they always find plenty to choose from.
As other reviewers mentioned, there's seldom a wait and it's clean, well-priced and the service is good.
One caveat -- the infamous belly dancers? Not so much. So we avoid going Saturday nights after 7:30 -- like the plague.
