"Order: Nitro Cold Brew We’re not going to lie to you, we’ve had a pretty serious crush on Climpson’s nitro cold brew for some time now. While not technically an iced coffee, we'd be remiss not to include it. Only available at Climpson's industrial-looking kiosk at Old Spitalfields Market, the velvety coffee that gets pumped from the tap here looks like a glass of stout and tastes just as smooth and just as rich. It’s easily one of the best cups of coffee you’ll find anywhere in London." - rianne shlebak, oliver feldman
