"Polo Bar’s door is wide open any time of the day or night, metaphorically that is, as it doesn’t actually have one. The joint is open 24 hours, seven days a week (except Christmas Day when staff board up the entrance) and has a food and alcohol licence to match. Have a beer with an all-day traditional English breakfast at 4a.m. or a glass of red with a burger. The only caveat to the 24-hour booze service is that diners have to order food with a drink between 3a.m. and 8a.m. Nachos and tequila, anyone?" - Daisy Meager
