Been to a very similar establishment in Zurich - which doesn't help, I know.
You go in through either a 'private' door, so nobody sees you - or into a pretty large bar.
If you go in the private way you get a line-up of girls you can choose from. All do OWO, anything else is at discretion (and a Swiss £20 under the table).
If you go to the bar you sit around in a nice (and large) social place while girls in lingerie stroll around and chat to you. Drinks are - get this - FREE.
Wander off with a girl to a room, wander back - have another couple of drinks and then have the madam call you a taxi. Or another girl.
Only thing is it costs a fortune with the exchange rate.
This is the place in case anyone is ever that way:
External Link/Members Only ... more to the point, here are the girls:
External Link/Members OnlyA better class ... but for the equivalent of £300/hour you'd fucking hope so.
