Aviary
The capital has one of the best skylines in the world, so the only appropriate course of action to take is find the best place to see it. A great place to visit if you're a tourist in London, the Aviary Rooftop Bar & Restaurant not only delivers on an elegant bar, botanical cocktails and delicious food, they've got a 6000 sq ft rooftop to enjoy it all on. And even if the weather is behaving as it does, they've got heaters outside, so you can enjoy alfresco dining and beautiful sites no matter the time of year.
