Ambiance: Not so pleasant, not so clean and sometimes very smoke-filled.
Service: Very good. Good style of drawing beer. Polite and nice.
Selection: Almost every day new kind of beer. Very wide selection from small czech breweries to best foreign beers. But only one changing tap.
Value: Sometimes too expensive (especially czech beers).
My favourite tasting pub.
Edit: After opening Ochutnávková pivnice, changing beers in Netopır are now only from small-medium sized czech breweries. So I must reduce selection rating...
