Door charges are around $200 for 1 hour (Hush will be 220 if you are not a member ; Alpha you have to be a member (it's very cheap, you don't have to give your real name) usually they have 20 dollar discount on the hour, so 160? Or 180?)
Imo Hush has the best-looking and professional girl overall and the place DT is way nicer compare to Alpha DT imo. Also it's less likely to bump into other men.
