A good food place in t'Lakes seems about the same as in Surrey; I'm actually out of touch with London prices. Beer a bit cheaper but not miles. A good ale in the Drunken Duck was just over 4 quid, I think. Lager slightly more.
Which is pretty much what my local in Surrey charges.

Last time I was oop I ate here - very good but prices were what I would expect to pay in Surrey
