I had breakfast at the buffet, which was $20 with a Total Rewards card.
The food was o.k. Eggs were lousy. Bacon wasn't great. There were a fair number of options, but it was all very mediocre.
The service however (clearing tables, filling drinks) was very good.
If you can spend comp points or just don't want to leave -- I guess this buffet is fine. However, there are lots of better choices in Vegas.
