Talk to me about food markets DiS - I mean the ones on streets like your fruit and veg stalls, fish and butchers places, things like that. Anyone purchase from them regularly?

I'm in the 'market' (guffaw) for the answer to two main queries if you'd be so kind - is the food quality noticeably better than yer supermarket stuff? Are there bargains to be had if you know your price points?

OR... feel free to tell me about your favourite food markets to get the tastiest foods.....
Any LME ever had successful trips to Smithfields or Billingsgate?
