A five-minute walk from Mumbai Central station, Sardar’s Refreshments specialises in straight-from-the-streets, finger-licking pav bhaji. It’s hidden behind white barriers, but mutter “Pav bhaji?” to any passerby and they will point you in the right direction. Two metal plates arrive within minutes: one containing thick vegetable masala straddled by a slab of butter, the other with fluffy rolls so well buttered the bread’s yellow. Your arteries will tighten at the sight, but your stomach will thank you. Squeeze some lemon on top and dig in with your fingers.
