Looks nice :]] http://www.capn-jaspers.co.uk/menu.htm Check out the half a yard of hotdog :]] Looks easy.
I went to the barbican the other day, didn't see it there, so wnt on to Moorgate instead. Looks a decent enough munch, wonder if they do rooms as well.
cap'n jaspers is right on the barbican. its easy to find, if not ask a local! they seem to close quite early though, so id recommend going there before you start your evenings drinking!
