When it comes to good gelato-making techniques, the proof is in the pudding – or in this case, the ice cream. 3BIS knows this, which is why it makes two to four-litre batches of its flavours every day, from morning to night, using raw ingredients which it sources from around the world. You can count on the result being deliciously fresh, creamy gelato in traditional flavours like stracciatella and pistachio, and you'll also find Instagram-worthy cakes and other sugary delights. Get a proper Italian espresso, too, for added authenticity, and sit on the mint-green chairs outside enjoying the sounds and smells of Borough Market.
