Review for Seneca Niagara Casino & Hotel Review For Thunder Falls Buffet Google User May 30 '18 at 6:42 I am impressed with the Seneca Casino and it's buffet. I saw many different gaming machines my husband and I enjoyed. Friendly staff and clean restrooms. Since we have never been to this casino in Niagara falls we received free buffet and saved 62.00. it was also crab leg night and people were lined up for these. Oh wait here is the killer part all drinks are FREE! With alcohol or without.....just like Vegas...... please tip your server, they are working very hard. View full site to comment or like
