I like this!

Perhaps it's changed since, but the one in top-level comment here is the same as what's actually in the OP, does it need to be combined with anything?

I understand not liking 'the forgotten genius' (tell me who) but personally I think 'changed British food' is more interesting (and what the article is actually mostly about) than 'Alternative London', which coming to the article I don't know what means, as a Briton who lived in London for almost ten years.

Ok I made room for changing British food by dropping the hippy guru bits. Is it better now?

(Re your first paragraph - I didn't understand, sorry. If it still matters, maybe explain a bit further and I'll take another look.)
