We often visit by boat, but at times by car.Yes they do encourage park and ride,but there are car parks also.Okay something are not cheap,but the quality is good.My local large market is Woolwich,which as a child was very good.Lots of meat fish and veg.Many stall holders had been there for years.Always a interesting visit.Now sadly just a few fruit and veg stalls.Lots of stalls offering rubbish
