The Comedy Grotto is a night of laughs tipped by The Independent and The Sunday Times. Time Out praises its "consistently excellent lineups" that have "comedy connoisseurs drooling", and we have to agree. This time around they're raising money for the Mainspring Arts charity, with another lineup that's packed to the rafters with funny. Lineup: - Tom Rosenthal - Sarah Kendall - Lou Sanders - Rose Matafeo - Alex Kealy - Ian Smith - Ahir Shah Over 16s only. Please note that acts are subject to change without notice. Doors open: 7:30pm. Start: 8pm.
