Many years ago Amsterdam had a lot of topless bars, they were free to enter but the beer was way more expensive. I was there with a group of lads for a weekend and we were on a budget but decided we were going in one on our last night even if only for one drink. The beer was terrible, I can't remember the price but if a beer was £1 everywhere else it was £5 in there, and after the first couple of minutes staring at tits the novelty wore off and we just sat chatting, I'd just order a couple of prossies if I were you, they'll charge the same rate for serving drinks topless as they would for sucking your cock.
