N2 Lab

The 'bolas de dragón' (dragon balls) are a huge hit with kids. These chilly treats are dipped in liquid nitrogen, so when you eat them, thanks to the temperature difference between them and your mouth, you get to experience blowing out smoke, just like a dragon. At N2 Lab they also make smoothies and waffles, but the stars are the 'nitrolados', ice creams made with liquid nitrogen, which are illustrated as symbols on a periodic table. The space, in fact, feels something of a crazy laboratory when it's bustling. All of the mixers give off smoke. Their ice creams, more than six regular flavours and one that changes weekly, bear the gluten-free seal and some are vegan. The salted caramel is irresistible. Top tip: if you want nuts as a topping, ask for them to be folded inside the ice cream instead of sprinkled on top. It's a winner.
