I've never been to the Big Chill Bar and this sounds pretty interesting. Thought I'd post as a suggested meetup, but do let me know if it's not your type of thing or if the date is inconvenient as they seem to do this a couple of times a month. Here's the description:
Each Tuesday will feature some of our very own and best players jamming live! £2 for society members and £3 for non-members after 9pm (before 9 it’s free). If you need more temptation… pints are only £2.50 and for all you ladies the cocktails are 2-4-1.
There's also DJ Asian Hawk at the Big Chill on Friday the 28th playing Hip Hop and Old School.
