NSFW Which are the more upscale strip clubs in Portland, OR?

My friend is coming to visit me in Portland and we want to go to some strip clubs. I’ve never been so I don’t know which ones to hit. We don’t want to go anywhere too sketchy. Just somewhere where the atmosphere is laid back and the patrons are not too crazy drunk and grabby. Of course, the girls must be sexy and not look like they are carrying every disease under the sun.
