All the comedy clubs we use offer the best comedians on the circuit and are dedicated comedy clubs, not pubs with the landlord's dodgy mates taking the mike.
With the vast majority of the comedy nights turning into nightclubs once the acts have finished, you're in for a top night. It's simply science: laughter increases bloodflow and positive mood. The brain detects this as arousal. Once aroused, the brain is more susceptible to further arousal. QED: once the talent has been giggling their socks off for a couple of hours, you're in!
