Best high street for charity shops in London?

[MorrisZapp]

Looking for a good mooch in London, with a mix of charity shops and other interesting shops, cafes etc. Near a lovely park for bonus points!

Chiswick High St/Turnham Green Terrace is an excellent mooch

Marylebone High Street has good charity shops - high end clothes, but can be pricey. Excellent for a mooch though and the bonus of Daunts bookshop.

I love Marylebone High Street! I'll check out Chiswick, thanks
