Had the pleasure of visiting the sexy sauna club in Prague.
100 US$ to get in but bargained for some free alcoholic drinks.

Erotic (read full service)
30Mins aprox 77 US$
60Mins aprox 155 US$

You can stay as long as you like free soft drinks and food, I was there for shift change around 8.00pm so saw both sets of girls and was very impressed. 18 or so girls per shift. 8/9's for sure, they pick the girls well.
Sample 3 in the 7 hours I was there, very nice place recommend.
