Let me start off by saying I generally hate buffets. I would rather pay more to get higher quality food made to order instead of sitting under heat lamps for hours with people walking by and coughing in their general direction. That said, this is one of the least bad buffets I have ever been to, the other one that still exists being Wicked Spoon at the Cosmo. There's also the one that no longer exists, the Rio seafood buffet BEFORE it started to suck (back in the early 2000s; I got married and brought my husband years later but all the seafood smelled and tasted totally rancid) -- since it sucks now, I can't count that one anymore.
So which to choose? Depends on what you want. The Asian food was better at Bacchanal, while the Wicked Spoon's Asian food was terrible. Bacchanal has some small selection of okay dim sum and made-to-order noodles (udon, ramen, pho, and even laksa, which I haven't seen at a buffet before). The Wicked Spoon had better prime rib and other cutting station meats, and had ribeye steak, which Bacchanal does not have. Both have lots of tiny cute desserts, but Bacchanal has daan tat (Chinese egg tarts). They had a puff pastry shell instead of the usual crust which is like a cross between puff pastry and harder, shortbread-like pie crust.
The best things Bacchanal had to offer were
2.) Suckling pig with crispy skin - really fatty and delicious and not sweet at all.
and oddly enough the best thing there was
1.) Mashed potatoes with gravy - seriously, I know that is a weird thing to single out because you can get this anywhere but they must put crack in the gravy because I was sucking it off my fingers and debating licking it off my plate when no one was looking.
Finally, like I said about the Wicked Spoon, to me it's worth going just once to experience it. But like all the high-end buffets, it costs more money than it's worth, and is also not worth the 2+ hour wait. We only managed to get away with just a 5-minute wait to get in because it was on an off day (mid-week) in the off season (winter, between Thanksgiving and Christmas) at an off time of day, between 2-3pm.
Now we only have one more buffet to cross off our Vegas buffet list, the Sterling champagne brunch, and then I never have to eat at another buffet for as long as I live.
