I asked uon where I should explore tomorrow, and when I turned down Catford he said I should find a Dogford and go there.
I gathered some preliminary suggestions on IRC, and I now turn to LiveJournal to make the final decision. You can choose as many options as you like, but I'm only going to go to one of them, so ticking all the boxes is equivalent to ticking none of them. Isle of Dogs is intentionally omitted as I've been there quite a lot recently.
Please also feel free to suggest things to do in any or all of these locales. I like lunch, dinner, pubs, bookshops, and green stuff.
Edited to add: This is actually happening on Sunday or next week instead, so you can still vote. I'll close the poll tomorrow morning.
