Review for Seneca Niagara Casino & Hotel Review For Seneca Niagara Casino & Hotel Google User Apr 10 '16 at 6:28 Went to three sisters cafe and the casino. The only bad part was having to leave the restaurant and either pull out my ID to go into the casino or down a long hallway around the front entrance to use the bathroom. There should be a restroom in the restaurant. Other than that everything was great. Good food, good service, great drinks! View full site to comment or like
