On the third Wednesday of each month, London based science fiction fans gather at a pub in London. As of mid 2013 this is The Sheaf pub near London Bridge and Borough Market. Yes - this is a cellar bar. Yes, they have footie on the telly some evenings. But the beer is ok, and the food is good, and the staff nicely tattooed. (I mean the staff are nice, and some are tattooed).
By the way - this Sheaf was the replacement pub for The Wheatsheaf just round the corner. Each month we get between five and fifteen attendees. You don't have to be a member to join. I'd say "look for the lobster" but we haven't had a lobster at a meeting for some time. Why not contact us through the website and say that you are coming!
