I don't see what the issue with £4.20 a pint is? This is for a premium lager, ales are cheaper. Pretty standard London prices.

It's the same price or cheaper than the Dartmouth, Hob, Post, All Inn One (Honor Oak, possibly, not been there yet).

Same story in all the decent pubs in surrounding areas like Crystal Palace, East Dulwich etc.

In FH I think only the Bird in Hand and Capitol are cheaper, and they are pitched very much at the 'no-frills' end of the market.
