Sadly, the Duke of Edinburgh in Brixton does not serve it. In fact, the barman didn't know what it was.
However, Benson Blakes, in Bury St Edmunds, not only does serve it but, when C asked whether they had it were quite prepared to knock together a cocktail that contained it. This anonymous cocktail contained cream, crème de menthe, vodka, a chocolate liqueur called Choco 21 which is unlikely to remain for very long at the back of anyone's drinks cabinet, really big ice cubes, a sprinkling of chocolate powder, and mint leaves. It looked like a mojito and tasted like pudding.

The classic crème de menthe cocktail is called The Grasshopper. Wikipedia claim it was invented in New Orleans. It sounds even heavier than that which has gone before - Crème de menthe, crème de cacao and fresh cream. A "Stinger", meanwhile, is 3 parts brandy to one part (white) crème de menthe. J is not sure he'd want to drink mint flavoured brandy but there's no accounting for taste.
