WHC in the Bay was a nice clean club. I was there for a year and it cost me 70 a month. That was a 3 years ago tho. It is mostly suits that go there. One or two bodybuilders. They played a lot of pop music. The staff was moderately friendly but nothing spectacular. A very large selection of equipment - though the dumbbell area would get rather hot in the summer as it was in an atrium.
Fifth Avenue Club I was at for a year and a half or so. The staff was incredible. Beyond super friendly. I never used the personal trainers so I can't comment on them. It was a clean place as well. The music selection varied. No Brittney and no Metal either. The selection of equipment isn't as good as WHC, but decent enough. It wasn't super busy either.
