I found Goldfingers to be very expensive even for entry compared to most places, but it is one of the better known ones in Prague ...
The one called Carioca I mentioned earlier is brilliant ... it doesn't look great from outside but the girls in there were some of the best I saw in Prague!
It was really cheap too .. I think I was £10 for entry but you got 5 free beers (half pints) included...
Just found a link for it:

Oh yeah, and I forgot to mention before ... If any of the girls ask you to buy them a drink.. politely decline as they only drink their (special) drinks which are nothing but fruit juice and cost about 3 times as much as a regular drink ...
