In Brno, Czech Republic, the transport company and a local brewery has
fitted out a tram as a bar.

It's in Czech, but the images are good.

The first screen asks if you are over 18. Just click on "ano, bylo" and it
will take you to the main page.

Of note. The tram trip of about an hour takes 55 mins round the city
centre. It costs about $2.50 for the ride and $1.90 for a half litre of
beer...but it is Starobrno. (Add snobbish sniff here).

I am quite put out because I had booked to be in Brno in about a week.
