If you've worked alongside the same people for any length of time, chances are you'll retire after the working day on Friday for a cheeky drink. It's a time honoured British tradition that helps grease the wheels of any organisation, and ensures everyone gets away early in time for the weekend.
But while sampling a quick pint (or three) is one thing, an afternoon of mixology is quite another. It's an experience that manages to retain the overall feel of your Friday night drinking sessions - albeit with a little more class, however.
Your ideal venue for an activity for like this is 69 Colebrooke Row, which is hilariously entitled The Bar With No Name. Try telling that to your cab driver. A suave, sophisticated Islington venue, this has all the class needed for an enjoyable evening.
With your work buddies, head behind the scenes of this popular establishments to the backdoor laboratory of bar supremo Tony Conigliaro, who is noted worldwide for his dedication to the mixed drink.
While you can, of course, expect all of the old favourites - a martini for Sarah, a mojito for James - you'll find a host of delicious creations that sound as though they have just emerged from the kitchen of Heston Blumenthal.
Take, for example, the Terroir, which has ingredients that include distilled clay, lichen and flint. Other must-try mixes include Guinness reduction, paprika bitters, rhubarb cordial and pine-infused gin - you'll have a chance to sample each one after the mixology lesson.
Where decor is concerned, a rich jazz-age vibe is adopted throughout, with smartly clad bar staff and vintage advertising posters adding to the aplomb and atmosphere that you require for a work do.
If you're looking for an equally classy way to get your staff there, consider calling Kings Ferry, who will serve you right through the labyrinths of London.
