This is one of the best cocktail bars in Sydney. Accessed via an elevator from the ground floor of Establishment, when the doors open you'll be greeted by a jawdroppingly stunning host and led through a sprawling Ottoman era-style room, with trapeze artist-high ceilings, soft seating, dim lighting and a DJ spinning sultry lounge. Hemmesphere is a bar for those with refined tastes and this is reflected in the menu - it's exquisite, with hand-cut ice, premium malt whiskies, cognac, brandy cigars and vintage Champagne. Nibbles come in the form of a delicate Japanese menu from the adjacent Sushi e restaurant (see Restaurants). All in all, you'd be hard pressed to find a better venue to ply your object of passion with exotic cocktails. Expect to part with a bit more bread than you would elsewhere, but it's worth it.
