From an "in Call" perspective, I know that Adam & Eve seems like a decent place - they have a nice manager and all the ladies I have seen there appear to be pretty, kind, and healthy.
I read here somewhere that they don't mind someone that wants to work there Part time either.
For this place, you may want to PM some of the ladies that work there directly (for discretion - yours and thiers)
Kimmy and Sweet_Stacey work there, and the Manager is also a paid memebr here.
From an "out call" perspective, I know that there is Carmen Fox - a few former workers from there are on this site as well - drop them a PM too perhaps.
There are many others, and some have had some issues of one sort or another.
Best bet might be to do an advanced search of this forum using the agency names as the keyword. - You will also gain a greater contact base as many of the reviewed ladies here do work or have worked at several of the local establishments and you can PM them.
Good luck and welcome to the area
