MissImp perform at Glee on the last Friday of each month - high quality improv comedy which is well worth seeing at least once, for a cheap night out. There's usually only very minimal audience participation (so long as you don't sit right at the front!) and you can shout out suggestions if you wish.
Their site is here if you want to check them out: http://missimp.co.uk/
Doors open at 8pm, close at 8.15pm and the performance is from 8.30 until 10.30. It's a nice venue with a bar and food. We expect to go to the pub afterwards for a drink (and a chance to make our own comedy).
Tickets are £6 on the door or £4.50 in advance. Arrive early if possible as this month's event may have a lot of people attending!
You can find Glee by the canal (NG1 7EH), tucked away behind Via Fossa - very near the Broadmarsh bus station and the Canalhouse / Fellows, Morton and Clayton pubs.
