Most visitors lose it to the hotel and the minibar. It is the most valuable evening of the trip. Notes on beginning London properly.
The first evening in a city sets the terms for the whole visit, and most travellers spend it recovering — room service, a call home, an early night that jet lag ruins anyway. A mistake. London introduces itself best in its first few hours, when everything is still slightly unreal and the city is lit like a promise.

Start with height: a rooftop bar, a high dining room, anywhere the city arranges itself below you — Westminster glowing, the river bending through it. Twenty minutes and one glass at altitude does more for your sense of the city than a day of streets. London from above is a map you will spend the week walking into.
Not a tour — a stroll of a mile at most, chosen for atmosphere. St James’s at dusk, when the shop windows glow and the clubs keep their secrets. The river from Westminster to Waterloo bridge for the full postcard. Mayfair’s side streets, where the city is at its most composed. Arrive somewhere warm at the end of it.
Book before you fly: the first-night table is the one most worth reserving. Somewhere with low light and unhurried service, close enough to the hotel that the evening ends gently. Order the thing the room is known for. You are not eating dinner; you are confirming the decision to come.
Whatever the flight did to you, be out by seven and back by twelve. The city rewards the effort on the first night more than on any other — and the trip that starts well tends to stay well.
A city is a different place when someone in it already knows you. Ask before you land.
