The Comedy Grotto is a night of laughs tipped by The Independent and The Sunday Times. Time Out praises its "consistently excellent line-ups" and this one's a belter with BBC Three sketch stars Birthday Girls, Edinburgh Comedy Award nominee Sam Fletcher, Chortle Award nominee Rachel Parris and Lolly Adefope. It's even free entry, though donations welcomed after in aid of Syria Refugee Relief. Over 18s only. Valid ID required. This event is free and entry is on a first come first served basis, so it can't be guaranteed. You need to be registered to store the event information in your profile, but rest assured, we won't charge you a penny.
