Geales' calls itself one of London's finest fish restaurants, and if its neighbourhood is anything to go by, that's probably right. They have two branches, one in Chelsea and one in Notting Hill. Founded in 1939, their ethos is simple, to celebrate great British cuisine. Their fish is sustainably sourced, and as well as putting a bit of a posh twist on the staple fried fish and chips, by serving it with tartare sauce instead of ketchup, they also provide other fish lovers with dressed crab, fish pie, whitebait and that seventies favourite, the prawn cocktail. If you've still got room, they do great British deserts too, treacle tart, apple and blackberry crumble and vanilla cheesecake.
