Yes, London, you heard correctly.
Famed cocktail-spot The Gibson will be giving away £1 martinis this week.
Marking the bar's third birthday alongside the inaugural World Gibson Martini Day (an event put together by the Clerkenwell bar with Copperhead gin), this century-old concoction is made from gin and dry vermouth alongside a baby onion.
Not only will guests enjoy this bold and slinky drink in one of the city's best bars, sales are being donated to gender equality charity, The Fawcett Society.
Hurry though.
There are only 1,000 martinis up for grabs.
The Gibson will be serving drinks on Tuesday 20th November from 5pm until late in celebration of World Gibson Martini Day, the bar can be found at 44 Old Street EC1V 9AQ.
