Review for Seneca Niagara Casino & Hotel Review For Seneca Niagara Casino & Hotel Google User Jun 5 '17 at 23:40 We conversed with a very polite employee on the elevator and wished us good luck upon arrival to the casino. I enjoy the large selection of slot machines and that there are smoking and non - smoking sections. We always enjoy the buffet, and the great variety of foods. Always a great experience.
