It was the Golden Age of air travel, hassle-free and the epitome of glamour.
And one innovative family hope their new eating concept will give diners a taste of what it was like to be part of the 1950s jet-set with a series of pop-up restaurants in west London.
Cousins Anna, Ollie, Will and Ed Templeton say Mile High will replicate the glitz of an airplane city break in that bygone era.
The restaurants, at secret locations, will represent the food and culture of four destinations - Gothenburg, Beirut, Sicily and Mozambique.
'Air hostesses' in Pan Am-inspired attire will welcome guests to the 'departure lounge', where they will 'check-in' with Campari cocktails and 'gourmet' bar snacks before 'boarding' the dining room for a four-course meal.
The family are drawing on the success of pop-up restaurants in east London and say diners will enjoy an entirely new concept.
Chef Ollie, formerly of Moro, said: "Mile High will bring an extraordinary culinary and creative experience, unlike anything else the area has seen before."
The family have enlisted art director Duncan Cargill to theme their restaurants, which will be at a series of secret locations. Cargill has helped shape brands including Selfridges and the Tate gallery.
Mile High's first destination will be Gothenburg in March, when dishes will include combinations of Swedish staples including Crayfish, Brown Shrimp, Smoked Bacon, Soured Cream, Dark Rye and Tarragon and delicacies like Lingonberry Ice Cream.
While dining, the cabin crew will provide entertainment, which the family says will give guests an evening of 'escapism and style'. Non-diners can enjoy cocktails and music from DJs.
Beirut will follow in May, Sicily in June and Mozambique in September.
* The first event takes place between March 13-16 and March 20-23, with tickets costing two cocktails and a four-course dinner costing £65. Drink only tickets cost £15. Book at www.dinemilehigh.com
