Here are some things I like: secondhand bookshops, the Prince Charles Cinema, XKCD, Manchester United, beer, science fiction, talking late into the night, the theatre, Tunnock's Caramel Wafers, discovering a new band or author, bouldering, and pottering around the kitchen listening to the cricket. I like cooking for friends more than eating out. I prefer pubs to clubs.
Films: The Apartment, The Magnificent Seven, It's a Wonderful Life, Singing in the Rain, My Neighbour Totoro. Anything with Jimmy Stewart.
I don't watch that much tv any more, but favourites include The West Wing, Battlestar Galactica, Veronica Mars, Misfits, Farscape, The Shield, Black Books, Breaking Bad, The Thick of It and The Daily Show. I've enjoyed the recent influx of foreign dramas, including Borgen, The Bridge and Spiral.
Radiohead, Jeff Buckley, Led Zeppelin, Joni Mitchell, Nick Cave and Neil Young are the basics. The last gig I went to was Shonen Knife which was fantastic. Update: now the last gig I went to was the Tune Yards. Equally fantastic.
Foodwise I like: my Gran's cooking, cheese, indian food, and basically anything sweet. I'm incapable of passing a shop selling gözleme without getting one.
