Fresh produce market(s) - London
Visiting from Montreal....looking for great fresh fruit/veg market.....am happy with different ethnic markets as well....
Again, would be helpful to know where you're based.
Borough is the obvious choice - expensive but worth a look if you're a visitor. Otherwise Brixton market is pretty good for most things. I even saw a couple of American tourists there the other day!
There's a Sunday market near Marylebone High Street on Sundays. We looked at it last weekend as we were in the area, but I was underwhelmed. I'd head for Borough where the supplies and varieties of goods is much larger.
