Nata28

You're wandering through Camden Lock Market on a Saturday, a bit knackered from the crowds, when you spot the queue at Nata28. It's worth joining. This is a proper Portuguese café that doesn't mess about with its natas—the pastry is shatteringly crisp, the custard filling isn't oversweetened, and the cinnamon dusting actually means something. They do a solid cortado too, the kind where you can taste the coffee rather than hot milk doing most of the work. It's tiny, tucked into East Yard, but that's half the charm. You're eating standing up, shoulder to shoulder with other people who know what they're doing.
