I agree it OP that the Bellagio's buffet is one of the best in town, if not THE best in town. Venison, NZ Lamb, Beef and Chicken Wellington and a Kobe Beef roast are offered most every night, except special event nights where the eclectic meny can include live Maine lobsters, softshells, and on the very rare occaision, Kobe steaks.

Living in Vegas, I've had the opportunity to try out most of the buffet's around town and the one that tends to be missed is the Village Seafood Buffet @ the Rio. (most people find the Carnival World Buffet and think that's the only one). As a seafood lover, I'm a big fan of the VSB which offers all you can eat Snow Crab, Lobster Tail (slipper), Oysters (on the half and Rockefeller) and a plethora of other choices.

If you're new to Vegas, both of those are must-hit, though a little pricey.

I have a free invite to "The Buffet" @ Wynn for next week, I'll come back and write a review then.
