How much does a pint cost now?
When I went to the first festy there in '95, a little village called Hostomice, we got steak, egg, mushrooms and chips with a pint of lager for about a pound.
That CzechTek was tiny but next year was massive. Every café had literally scores of crusties sitting on the pavement outside eating steak and chips, all day for the whole week.
Bet it costs more, now. Be a tourist and go and have dumplings in Wenceslas Square.
