Oz Clarke and Hugh Dennis scour the British Isles for the best drinks with a view to opening a traditional pub of their own packed with tipples from England, Ireland, Scotland and Wales. When they fail to agree on what the best drinks are, they open two bars that go head to head for one night only. Their tour of Gaelic grog kicks off in Perthshire, where a visit that begins with wine tasting (the nonalcoholic fruit variety) ends with a bottle-smashing competition. To continue their research, they head for the Inner Hebrides and Easdale Island's popular, and only, pub. Next stop is Ireland - north and south - where Hugh's embarrassing confession to liking Irish Cream leads the pair to make their own version of the drink.
