Eighteen Sky Bar
Sat 18 floors above the Thames, Eighteen Sky Bar is a gorgeous cocktail bar right by The O2. Their floor-to-ceiling windows look out over Canary Wharf and London's beautiful skyline, especially lovely at sunset.
There's also an open-air terrace to explore, and there are regular DJ sets here too. Their innovative cocktails include a Berry Pop or the Forbidden Fruit, paired with small plates like British charcuterie boards and crispy fried sushi rice.
