Review for Roxy's Casino Review For Mystic Lake Casino Hotel Google User Jan 24 '18 at 1:03 Went for the buffet brunch. Was pleasantly surprised at the variety and the quality. Although it was a casino buffet the quality of everything was good. If you were to compare it to another "regular" buffet I'd rate it highly. The prime rib in particular was excellent. We will be going again. The only down note was they allow smoking in the casino which detracts from the otherwise good dining experience. Smoking was not allowed in the restaurant area and the smoke scrubbers were able to remove all odors there. View full site to comment or like
