Went in the Bier Keller the other weekend. Found it ok. Sat in the downstairs bar, the one with all the beers, and it was decent. Atmosphere was good at around 5/6ish after doing a bit of shopping with the girlfriend. As for the ale tho, I think the fly in the loaf is a better pub, more draught and a better selection. A lot of the beer I had tried/I didn't really class as a world beer because of it's uk popularity such as Corona!
