Well i mostly see bands in a pubs ( suprisingly ) so i'd say The Druids Arms in Maidstone is always good for a band as they have a court yard out the side of the pub which is covered and has heaters so you can jump around to the band like a complete loon whilst still being able to smoke and stay dry and warm. Job done.
Went to a gig down the Lee's Cliff Hall in Folkestone in the week... wicked night altho the venue is a bit toilet but kind of love it for that lol
