If I'm wrong here please correct me.  But a true Amp would have a mamasain up front and you would be able to pick your own girl, with different menu options?  Is there any thing like that here in the twin cities?  I usually go for independent providers but would like to try something new.  
Thank you for any responses and feel free to pm me.

Usually they send you to a room, and a gal comes in of their choosing.  If you like that gal, you can get her name and when you call for an appointment, request her.

This is how they do it where I live in the Northeast.

The AMP's in the Twin Cities suck.  Don't waste your time or money.  Try backpage or some other reliable indy sources.
