Parked right by Liverpool Street station, this 24-hour café has been around since 1953 and shows no sign of slowing down. Blessed with a 24-hour alcohol licence, Polo Bar feeds the City’s hungry with a vast menu of British comfort food classics. In the early hours, breakfast sandwiches and pancake stacks (including a cookies and cream option) reign supreme, while come dinnertime, heartier dishes take over. Pick from the likes of steak-and-ale pie, or a chilli cheese burger which comes with bacon-and-cheese-loaded chips. If you have any room left for dessert, a range of bakes including red velvet cakes and warm chocolate brownies is available. A simple afternoon tea option and bottomless Prosecco weekend brunches are also on offer, making this a viable City hang-out which never sleeps.
