Not in terms of beer, but if you're happy with lager it's great. We went in one place and just wanted a quick half before grabbing a bite to eat. Apparently the only measure they do is a two-pint jug. Oh well, when in Rome.... Somewhere else was absolutly enormous, the capacity must have been about 1,000.
I'll try and dig out some names. It's a lovely place and I'd like to go back. Oh yes, and you have to have curry sauce with your bratwurst.
