I've had Bellagio and it's very, very good. But, I prefer Paris. It's about $10 cheaper for dinner from what I recall, but the food espcially the deserts cannot be topped. I don't think Paris can be topped.

MGM's is adequate at best. Harrah's is poor. Unfortunately I stayed there on business and had coupons for free buffets with my room.

Mirage has a very good one. Equal to Bellagio IMO.
