I went here for breakfast and dinner. I would have to say I experienced the same meh experience both times. Although they had a variety of food, it did not look fresh. The food looked like it had been sitting out, and was not refreshed. I am not going to eat, nevertheless gorge myself on something that looks unappetizing. I suppose you get what you paid for. If I was staying on the strip, I would not venture out of my way to go to this buffet, and if I stay at the Palms again, I will not return to the Bistro Buffet. If you are a visual eater like myself I would steer clear of this place regardless of the price, but if you are that kind of person who will eat anything then this is a good place to go.
One thing that I found very irritating about the line to get into the buffet was that they did not make hotel guests priority. They had two lines for non-hotel guests, and hotel guests, but it didn't matter because they just took one group from each line after another. I think that if you are staying at a hotel, then the hotel guest should be the first priority to getting a seat.
