Let’s just admit it, shall we? Most rooftop bars in central London usually suck. Most of them are usually a scene, or full of daytrippers from Slough, and you’ll be lucky if the view includes anything better than a few other rooftops and the odd naked person. The good news is that Sisu (formerly Notch) exists, and is one of the better options in town. There’s a large terrace with plenty of space for groups, a laid-back vibe, and while the drinks won’t blow you away, you do get a lot of bang for your buck. There isn’t a lift, so bear in mind that if you’re dressed to go out out, you might arrive looking like you’ve just come from a spin class after climbing five flights of stairs.
