normally, i go to sainsbury's or so to buy lunch, but now we've found something much better: there's a bakery very close to school. they do quite good bread, at least for england ;), and you can put together your very own sandwich - best thing, they have student discount and it's cheap anyway, and you can sit in there:

and they have delicious puddings:

chocolate caramel shortbread

chocolate cream swiss bun (i asked them why it was called swiss bun - they said that it was just a random name... weird english people)
