Early twenties: ten companions with a full diary of interests

Late starts, West End

Molly begins around 10pm and is still good company well past midnight. Jasmin likes the hour after the theatres empty and a classic cocktail. Stacy is glad to hear from you at nine about a night starting at ten, comedy first. Angelika opens her diary at seven and heads for live jazz. For bars and music before the hotel, read night out company.

Straight after City hours

Tiffany is most open midweek once the working day ends, with champagne and a photographer's eye for a good room. Bianka prefers a proper dinner with a day of notice and reads a wine list properly. Lucy is free day or evening midweek and will point out a planet or two from the Sky Garden. All three know the City of London hotels well.

Curtains and openings

Lea is a theatre regular, easiest to book midweek before a show. Luna keeps track of every new production, studies wine and prefers Monday to Thursday. Between them they will know what is worth seeing this month and where to eat afterwards.

The airport name

Roxi is the one in this band who favours Heathrow. Boxing in the morning, surfing whenever she can get out of London, three podcasts a day, and no complaint about a flight that lands two hours late. Her profile shows her current availability.

A late evening, as it usually runs

Ten o'clock: a message with the hotel, a time and a name or two. Within 15 minutes: a reply saying who is free. Around eleven: a drink downstairs, or straight up if you prefer. Two or three hours later, goodnight at the lift, or an extension if both of you want one, priced from the same board.

Choosing between the ten? If the night is loud, look at the first group. If it involves a table, the second. If there is a ticket, the third.

What this stage brings to an evening

Conversation here runs on what is happening now: a gallery show that has just opened, a bartender who has moved venues, a comedian worth catching before the tickets go. Plans change easily and usually for the better. If you want a more settled pace, the late twenties and thirties and beyond lists are the place to look.
