Petite companions for E14, by the seat each one makes for

Jasmin claims the corner stool at Bōkan, the bar crowning the Novotel on Marsh Wall, and asks the bartender for something that is not on the list. Chestnut hair, quick brown eyes, heels for a few extra centimetres. She prefers to begin after nine and is good at short notice, so ninety minutes at £400 covers one round while the towers go dark.

Lea wants the stalls at Theatre Royal Stratford East, near enough to read faces, far enough back to take in the whole stage. Auburn waves, hazel eyes, soft romantic dressing. She studies every note in the programme and delivers her verdict over supper. Midweek, two days ahead, is the surest way to get her the seats she likes.

Lucy starts on a riverside bench at the southern tip of the Isle of Dogs, with Greenwich laid out across the water. Dark curls, an espresso habit, a star chart in her pocket. From there it is down the spiral stairs and under the Thames on foot. Daytime and midweek evenings are when she is simplest to book.

Rosa begins at the café of the city farm on the Isle of Dogs, towers rising behind the paddocks and cake on the table. Chestnut curls, a generous laugh, a crate of records nobody else wanted. As the light fades she walks you to a riverside pub terrace for a long supper. Sunday to Thursday, from the afternoon.

Sonya picks seats at Sadler's Wells East with a clean line to the dancers' feet, because that is where the work shows. A dancer's carriage, hazel eyes, very dark hair worn straight. She watches in silence and afterwards describes the moment that stayed with her, never the technique. Her window runs from five until ten.

Tiffany likes a low table in the warm bar at Tribe, near the squares, where she toasts the close of your day with champagne as the towers empty. Chocolate brown hair, braided or loose, and a little sparkle somewhere in what she wears. Midweek, straight after office hours, is her time.

Tina takes whichever table sits closest to the stage at Big Easy on Crossrail Place, bourbon sour in hand, and links each song to the record it borrowed from. Espresso brown hair, a fashion designer's eye, and more energy than her 158 cm might suggest. She can often say yes on the night.

Every seat costs the same. Sixty minutes is £250, an hour and a half £400, two hours £500, and the rates page lists everything longer. Lea and Rosa both favour long, warm evenings and appear on the girlfriend experience itinerary. Sonya and Tina also stand on the toned and athletic floor, and four of the seven, Jasmin, Lea, Lucy and Tiffany, are on early twenties.
