There is little novelty now in food blogs which take a single, tiny area of the nosh world and plough them into entertaining furrows. Nevertheless two blogs by Russell Davies take the art of obviousness and raise them to truly stupendous heights.

a good place for a cup of tea and a think
Which catalogs tea-shops, coffee houses etc (and whose title, whilst reminiscent of a nice cup of tea and a sit down does specify that it is much more about the place than the produce)
and
eggbaconchipsandbeans

(Found when looking for a caff by Marylebone Station for breakfast before the Cricket tomorrow: Gino’s looks the ticket.)
