Review for Sherwood Valley Rancheria Casino Review For Seneca Niagara Casino & Hotel Google User Nov 25 '17 at 0:03 First time visitors from Texas. Went on Thanksgiving for something different. We were pleasantly surprised when the hostess offered 2 free buffets for signing up for members club. Was an awesome experience for us. We decided to try a little slots. Put in 10.00 and played. On the last pull, all kinds of lights and buzzers went off and my fiancee won 110.00. We will be back. Everyone of the staff was on their A game, and for it being a Holiday that's a plus! Good job Seneca Casino! View full site to comment or like
