What club(s) in Niagara Falls, Canada is 18 and over?

I have friends coming up from NYC to Buffalo. We wanted to go to a club(s) in Canada but my friend's girlfriend is only 18. Besides the few clubs in Buffalo on Chippewa that I know about, what are some Canadian Clubs that we can go to? Also are there any other Buffalo clubs that are a step up from the Chippewa Clubs that are also 18+ (something like SkyBar)? Maybe there's a website that could make this easier? But I've just about Googled my butt off... Thank You
