Champagne brunch at the Bellagio on Sundays = pretty fantastic! Don't plan on doing anything afterwards because with the amount of mimosas you'll have consumed (they keep them coming) you'll need a nap after this brunch. I've been 3 times now and the food is always excellent. They have breakfast and lunch foods, and the food is nicely varied. The dessert bar could give anyone a sweet tooth (or diabetes) and the salad bar look super fresh. Do yourself a favor and go just once to say you've gone.
