Do you mean the clip-joints, where men are enticed in on the basis of a cheap drink / dance / chat, and end up being presented for a bill of ?250 a drink (including the fizzy squash they've bought for you as 'champagne')?
No, they don't have websites. Odd that.
Other ones are strip clubs, where you'll be paying a couple of hundred pounds or so a night and expected to make a profit yourself.
