If you live in the Stratford or east London area you should do what I did last night. I went to Shkar Sharif's new kung fu club in Stratford. It's a quick walk from the Stratford station and getting to Stratford is quite easy for me thanks to the Waterloo & City line + the Central line. Doesn't take long.
Shkar and I have been training for many years now together under Dave at the City & Islington club; Shkar a bit longer. Last year, Shkar took his instructor grading and has now started this club on his own (with some help from Dave). He's been running this club now for only a couple of weeks but is (t)here to stay. I genuinely recommend anybody in the area to come along and train there. At the moment he's only teaching kung fu (Fujian White Crane) at that venue but will soon have t'ai chi classes too.
If you want more details about the classes go to his club page See you in class!
