Vesterbrogade is Vesterbro's daily-shopping spine — the working-life version of Strøget, on the other side of Central Station and not for tourists. Halfway along, Værnedamsvej branches north for two hundred metres of French food — the little Paris of Copenhagen — cheese, wine, butchers, three good cafés.
Three kilometres, ninety minutes if you stop for cheese. Start at Vesterport S-tog and walk west on Vesterbrogade. Pass Vesterbros Torv — small square, market hall — and on to the Værnedamsvej turning, half a kilometre west.
Værnedamsvej itself is short — barely two hundred metres — but the density is the point. Ostebørsen (the cheese exchange) is the canonical anchor; a butcher next door; Falernum or one of the natural-wine shops a few doors along. The cafés put chairs on the cobbles in summer. Walk slowly; eat as you go.
Cut back south to Vesterbrogade and walk west to Forum metro. The cheese gets you home.
