The top two floors of the iconic Gherkin skyscraper were once reserved as a private members' club, but now anyone dressed to impress is invited up. Cocktails in the 40th-floor Iris bar under the oculus roof with 360-degree views of the City are a sight to behold. On Sundays, Helix, the restaurant on the 39th floor, is open for a sky-high brunch.
Advance booking is required.
