Central
Café
2700 board games for you to play; tea, coffee and cake to sustain you. You pay a cover charge per person, and can stay for up to 3 hours. There's plenty of help choosing (and setting up/playing/learning) games, and some for sale if you can't bear to part with them.
If your friends are all philistines who don't like board games, or you just want to meet some new people, Tuesday evenings are open gaming so you can come and join a group and maybe play something new. The fourth Sunday of each month is PlayTest, where you can bring a board game you are designing, for members of the public to play and give you feedback.
