Trevi Italian Tiramisu

You'll find yourself on Bute Street, that quiet corner of South Ken where the crowds thin out and you can actually breathe. Walk in and you're hit with the smell of quality espresso and cocoa dust—it's unapologetically focused, the sort of place that doesn't do croissants or cappuccinos because they're too busy perfecting their one craft. The tiramisu comes in proper Italian iterations, the kind that makes you realise most others you've had are basically just dessert fan fiction. At around £5-8 a slice, it's not cheap, but you're getting the real thing—proper zabaglione, proper layers, proper respect for tradition.
