We've long sung the song of Gillray's Bar as one of the merry kings of cocktails; now here's an exclusive chance to get the know-how from the masters themselves. Through an informal, hands-on session guided by the County Hall Head Bartender, create (and drink) two fine cocktails from Gillray's dazzling array of more than 70 gins and spirits. You'll even learn how to make them at home – no special equipment needed. And then there's those views of the Thames and Big Ben to admire, too. Pretty neat, huh? Best available seating allocated on arrival. Over 18s only.
