We visited this buffet on Easter Sunday. Although the place was packed, we had no problems.
Since we were in town for an event, we decided to forego the exorbitant prices for food at the venue and have real food--salad, vegetables, etc. We ate enough to last us the better part of the day! There are so many choices that it is dizzying to comprehend how the staff keeps up and knows how much of each thing to prepare.
Note that of course this is not a gourmet restaurant, but anyone who could not find something to like should just probably stay home. I particularly liked the coleslaw, the steamed asparagus, mashed potatoes (not the potato casserole) and the pies. They have everything from seafood/beef/chicken to pizza and Mexican food. They are also open fro breakfast on weekends. Though our server was frantically busy, she kept our water glasses full, and she took time to visit with us briefly as well. This is our go-to place when we are in Oklahoma City.
