The Buffet at Rainbow is open now only on the weekend. Monday through Thursday the Buffet is closed. Buffet opens around 4PM on Friday and closes about 10 PM. Friday is a seafood buffet, but the price is steep. It looks like the Saturday and Sunday Brunch is reasonably priced. I think Saturday open is about 7 AM to about 10 PM. On Sunday the Buffet closes at 3 PM.
