In better English, I was hoping to say something along the lines of:
Hi Adel & welcome to Bristol!
Excuse my French - I'm writing without a dictionary!
I know that there are hip hop classes at The Bristol Dance Centre, but it's in Hotwells and therefore quite far away from Bishopston. I don't know if the classes are for children or are just adult only, but there are contemporary dance classes especially for children on a Saturday morning.
There is also a hip hop school:
I hope that helps!
Finally I should really say that you should try Le Roc! There aren't any children's classes but there are loads of classes for adults - practically every night in Bristol! It's great - we love it

My French is a bit rusty though and grammar was never my strongpoint, so apologies to Adel!
