Each celebrity in attendance was there to celebrate 10 years of the Chiltern Firehouse. The venue was founded by hotelier André Balazs and opened in late 2013.

It is well known as a trendy celebrity hotspot and often attracts big-name stars who are looking to enjoy a night out away from prying eyes. The hotel/bar/restaurant has one of the most sought after menus in the city incorporated into it, as well as an elite VIP bar.

The Chiltern Firehouse is a five star residence that boasts 26 suites and lofts with a nightly cost ranging from £770 to £1610 and more. The residence gained its name from being built in the red-brick gothic building that originally housed one of London's first stations.

The restaurant is looked after by Head Chef Luke Hunns who "has created a fresh menu of reimagined classics and bold new flavours, placing emphasis on seasonality and healthy eating," according to their website.

Those wanting to eat at the hotel are advised to make their bookings in plenty of time, with tables often required to be reserved from two months in advance due to the popularity of the venue with the rich and elite. The menu has everything from pizzas to an £160 Aberdeen Agus ribeye steak, a £145 oyster and seafood sharing platter, and a £2000 serving of Beluga Imperial Caviar.
