Visited the Winter Gardens December 2012 to see Keane in concert, having seen the same band at the O2 3 days previously. This much smaller venue was great, a short queue outside to get in (probably because we were a tad late, the support act was already on stage as we got in). Quickly through security and quite efficient cloakroom. The hall itself was lovely and I really enjoyed standing in a crowd of good humoured fellow enthusiasts. Adequate loos easily accessible from the hall, cheerful bar staff with reasonable selection of drinks, albeit pretty pricey. Fantastic atmosphere during the Keane set, both the audience and the band seemed to be having a great evening. Bit of shuffle to get out afterwards, which I found a bit worrying had there been an emergency evacuation, and the queue to collect coats moved slowly...hey ho, a minor point.
Forgot to mention earlier, had booked the tickets by phone - a novelty for me as have always booked concert tickets online but Margate don't have this facility. Box office lady was cheerful and efficient, exactly as she should have been, but definitely worth noting and kudos to to the team.
