The Horniman

From Frikipedia

Hornily named pub near London Bridge station. Right on the south bank of the Thames, so the beer garden offers stunning views of the HMS Belfast, which is a garish, rusting old warship thing that doubles as an advertising hoarding.

Inside, the pub offers debatable beer and really quite stingy sharing platters.

Also nearby a riverboat "shuttle" stop, so you can go down to the dock, wait half an hour for a boat, then not be allowed on and walk back to the station.
