After its glorious summer sojourn (the most Instagrammed pop up of summer 2016? - we think so) Pergola on the Roof is back. This time the covered rooftop food court on the roof of the BBC Television Centre is heated for winter and a Nordic forest sets the scene. Dine at a choice of four self-serve restaurants under a canopy of holly, ivy, and winter flowers, set against burgundy walls and paved with woody bark. Think silver birch trees, low level lighting, blankets, cedar wood, oaky scents and candle light. Choose from menus by Snaps & Rye, Le Bab, Patty & Bun and Gunpowder. The queues were long over the summer but you can book in if you're a party of four or more, there's capacity for 600 and 25 per cent is kept back for walk-ins plus there are five giant beds seat up to 15 people. Snuggle up and get cosy.
