The restaurant that was doing steamed bao buns long before they became a citywide craze, On the Bab specialises in all kinds of incredibly tasty Korean anju (snacks to be eaten with drinks). A tiny corridor of a place, it's become a hot lunch spot for those who work within a one-mile radius. A fan who loves the spiced pork bao notes "it's not often I crave one particular dish", while others drop by for the deep-fried kimchi and cheese arancini as well as the staple Korean fried chicken with crushed peanuts and sweet chilli sauce. The plates (actually enamel camping-style crockery) come thick and fast and you're likely to be in and out in an hour, making this an ideal spot for a working lunch or dinner on the run – just remember it's a no-bookings eatery and the queues form early.
