When I worked at Great Ormond Street I used to drink in the Lamb on Lamb's Conduit Street, which used to be good. This is a few years back though...
When do you want to know by? Got a friend on Facebook lives in London and is a Camra member, always posting up pubs he goes to, I'll ask him! CAMRA book shows The Museum Tavern on Great Russell St, Also note it's in Camden and I know theres a Brewdog brewery place there.
There's a decent one but I'm ****ed if I remember the name. Down the road straight opposite the entrance to the Presidents Hotel. Has football on. Also there's another one just round the corner from that hotel, left from the entrance and left again.
