I've been to the feast buffet 3 times and the food is consistently mediocre. There is decent value here, but the food is as you should expect. You are getting what you pay for. That said, each time I've tried the feast buffet it's satisfied what I've wanted. Except the time I wanted a donut for breakfast and they ran out.
Because the buffet is a good value expect to wait in line. Especially during peak tines.
