I often travel from south Wales to south London for work. It’s a nice contrast and I really like both places. Brixton market is always a great place to go and walk and look, and perhaps eat. The main fish market is always busy and the selection is slightly more varied than at my local Tesco! I’ve seen bream, carp and even a chub once! I’ve always been drawn to fish counters and at a market in Helsinki I once came across a pike that was easily 20lbs up for sale.
