Caffè Nero

You're rushing through Euston, already mentally on your train, when you spot the Caffè Nero tucked into the Colonnade. It's the kind of place that doesn't pretend to be anything it isn't: a proper coffee stop where you can actually get a decent flat white without the faffing about. The queue moves fast, the staff know what they're doing, and frankly, it's a relief when you're surrounded by the station's perpetual madness. Whether you've got twenty minutes to kill or just need fuel before heading north, this does the job.
