MOLO Elephant & Castle

You're walking through Mercato Metropolitano's buzzing food hall in Elephant & Castle, past Italian delis and pasta stalls, when you spot the queue at MOLO. It's worth it. This is proper fish and chips done right: the batter crackles between your teeth, the fish inside is actually flaky instead of dense, and they're not skimping on portions. Sit at one of the communal tables with your paper cone, watch the kitchen work, and remember why this stuff is a national treasure. No pretence, no silly twists—just excellent execution of something simple.
