karate for 5 year olds

[pmTea]

Can anyone recommend a good class in Camden, preferably within Dartmouth Park/Tufnell Park/Archway/Upper Holloway area, for a 5 year old?
I've done a trial at Expressions dance studios (30mins long) and the teacher was very good, but once they'd all warmed up (20+ kids in the class, rather large) there was only about 10mins left of class time.
Age range was from 4-7, so teacher spent a lot of time policing, which didn't help.
Any other classes, maybe 45 mins, I've missed?
Thanks.

There is one held on Fridays 5pm at the Royal Free Recreation Centre. But term finishes 5 July, new term starts 13 September. It's a smallish class of kids aged 5-7 I think and lasts 50 minutes. my son loves it.

ooh thanks turk - will look into that - never even heard of the RF rec ctr!
