Writing this from the second time I came which is about a good little less than a year since it opened. First time I came with it was still barely new, I thought that this buffet was to beat from all the ones in Las Vegas. It used to be the Wynn Buffet for me until Bacchanal came about. Many great selection of food and dessert so what's not to love about it? Though this is all true from all hyped expensive buffets when it first opens. They expect you to draw you in with the many great selections and good food. Give it about a year later and the quality isn't as great as it once was. Since they know they're probably the buffet to beat, I don't think the service and quality of the food isn't on their mind anymore since they know people will come regardless.
Besides the great selection of dessert which I don't really have much complaint about, it's their food that can be better. One example is their prime rib which used to be tender and juicy but it has been dry as of late. However, though quality has changed a bit from before, their huge selection and taste of some other food are just or even better than other buffets I've been to. You still have food you can't find anywhere else and their seafood selection is one of the best. I don't usually do the 24 hour AYCE pass whenever I go to Vegas because one buffet for a weekend stay is enough for me and I would probably choose this buffet or the Wynn Buffet everytime I go to Vegas until something better comes along.
One thing that annoyed me was the server. From the time we sat which was about 30 mins in, there was no waitress/waiter to serve us. It ended up being the busboy helping us get our drinks and clearing our table. You can tell by the 2nd time we started asking for refills he was kind of annoyed because he knew that wasn't his duty. The server finally showed up 45 mins later but there was no point. All she did was come to clean out the dishes from our table. You'd expect better service when you're paying $50+ for a buffet.
