I've been there a couple of times. The club is clean, it has a great selection of equipment, and I never have to weight for the machines I want to use.
Ballys (The West Mall, Etobicoke) is a great gym for people who are serious about getting fit. I was a member there for several years. The gym is nothing fancy, but the training staff are exceptional. A lot of the members are very fit so it's very inspirational! I can't speak much to credibility because I paid in cash so I never encountered any problems that are typical of most gyms. I highly recommend this location if you are serious about getting fit and want quality instruction.
