"Sky Garden pairs epic views with tasty cocktails and an indoors garden, how can you not love that?. Sky Garden has a 360° view all around London and a number of different bars and restaurants inside it. Access to Sky Garden is free but you have to book in advance if you want to skip the queues, don’t worry if you forget about booking, you can still access Sky Garden but you will have to wait a little longer before taking your perfect Instagram shots."
