Duck & Waffle

You're riding the lift up 110 Bishopsgate in the early hours, watching the Square Mile shrink beneath you. Duck & Waffle occupies a dizzy 40th-floor slice of the Heron Tower—the kind of height that makes London feel manageable, almost intimate. They're serious about their namesake: duck comes twice (crispy confit legs, then a seared breast), and the waffles are the proper deal—yeasted, fluffy, not some Instagram afterthought. The menu stretches beyond breakfast too, all-day dining that respects both the 3am crowd and the expense account brigade. It's the sort of place that proves London's obsession with breakfast isn't actually ridiculous when you're served it against a view of St Paul's Cathedral catching first light.
