Like your champagne served with a breathtaking view? Situated at the top of Tower 42, this bar provides one of London’s best panoramic views of the city. Sure, you might have to book in advance. And sure, there’s a £10 minimum spend, but it’s well worth the vertiginous trip to the upper level of this building. Champagne is the order of the day, with prices starting at £59.50 a bottle. Those with more expensive tastes can also opt for a magnum of Krug Clos du Mesnil costing £920.
