When I stayed at the Bellagio last year it seemed like everytime I walked past it there where only a few people there at the most. Though tripadvadvisor reviews gave it a 4 out of 5. I would check tripadvisors website and read people's reviews.
Yeah, I tend to be more of a lurker than a poster around here!Circo actually has two rooms, the Alcove room is off the main dining room and faces the fountiains and the other (Saltimbanco) is near the entrance. The menus at Circo start a little lower than Sensi, around $75/plate and if you use the Saltimbanco room, you can also use the menu from Le Cirque, but those are a little pricier if I remember correctly. The room minimum for the Alcove room is $4500 and for the Saltimbanco is $2500 (I think). We ended up blowing a good portion of our budget on the Alcove room, but my fiance loved it so much that I just couldn't say no!
