I'm going to this thing...

...and I have a few questions

a) I've never been to the Windmill before. I take it I'll be able to get food in there?
b) How do I get to the Windmill from Brixton Tube? I could look it up easily, but this is much more a "who wants to meet me beforehand" hint
c) I bought 2 tickets because I was scared of DiSers. Now I'm feeling a little braver and may not drag a 'real' friend along. Anyone in need of a ticket?
