Review for Seneca Allegany Casino & Hotel Review For Thunder Mountain Buffet Google User Apr 12 '18 at 15:27 Used to love the Prime Rib buffet, not so much lately. Quality is down. Same food for years now. Expensive. As a smoker I appreciated having a smoking area that was well ventilated from the other patrons but that's no more.. Strange since its allowed on the gambling floor. Probably won't be going again. Better choices available at far less cost. View full site to comment or like
