Thekla was the first club I've ever been to and it really was a lot better than I expected. It was a very friendly atmosphere and the interior was fantastic, albeit a bit bland in places (though that's expected). It was 2 for 1 night when I went, which was fantastic as the drinks were so cheap. Entry was only £4 which is far lower than I initially expected of a club. The music was good, with two different rooms playing two different genres, perfect for anyone really. Very complicated layout and I was only aware of one toilet being present which meant it got very cramped. Staff seemed friendly and the drinks were well made/served. The layout of the club, as it is on a boat, is quite confusing to begin with, lots of narrow corridors and stairs, but after a while it becomes second nature as it loops back to the entrance. Smoking area is nice and big with a good view of the water front (provided you can see past the masses of people). Overall, it is a great venue, definitely worth a visit.
