Visited the Ariadne Club in Prague (Zitna 4 , Praha 1)
Very clean and quite spacious, with a restaurant as a bonus (meals are cheap 275 Kr). Tip of 50 Euros at the door got me first choice from the 10 + women working that night (opens after 7:00 p.m.). Nice facilities include jacuzzis and a large, well stocked bar (there is also S&M facilities I'm told). This must be one of the more popular clubs in the city, saw a famous American actor wining and dining a couple of ladies.
You can choose a companion right away or enjoy almost continuous strip shows and lap dancing (about 600 Kr/dance) from fairly agressive dancers.
I invited an escort, a brunette beauty who went by the name of Jessica, to accompany me to dinner and some companionship at my hotel. Three hours with full service cost 150 euros (I think a part of this went back to the club).
