Thanks for the suggestions. It looks like the Pizza Express is just round the corner from where we're playing so we'll have that as a backup option. Unfortunately Green Note doesn't open until 7 which is too late for us, but I'll bear that in mind for any future visits. Shame though because the band they've got on tomorrow looks interesting!
If anyone fancies any dancing, or just listening: http://www.barndance.org/ (it's not actually barn dance!).
