Cross post from AQA:

Does anyone know where I could pick up good oysters in North London which haven't been subject to a massive mark-up?

Eating them is on a friends "beore I'm 30 list", who is based in Crouch End and I'm in Stokey. Both places I'd have thought will carry a mark up on those sort of things. Steve Hat's in Angel is the obvious choice but that does tend to be pricey... and not always necessary ime.

Any suggestions?

Cheers.

Have you tried going to billingsgate fish market?
