A spate of new bars, from sophisticated rooftops to underground bunkers, is tempting revellers. Intriguing newbie Kittyhawk (16 Phillip Ln; thekittyhawk.com.au), is a stately space with a dash of WWII-era bravado. Order from the illustrated menu that brims with rum and rye concoctions, and inventive drinks like a ‘pineapple cobbler’. Concealed in an alley off George Street, Burrow Bar (De Mestre Pl; burrowbar.com.au), is a low-key basement space with sandstone walls, barrel-aged cocktails and craft beers. Prefer water views? Zephyr (161 Sussex St; zephyrbarsydney.com) is perched atop the Hyatt Regency, overlooking Darling Harbour, offering adventurous drinks like peach and thyme spritzes, pink grapefruit martinis and foaming nitro espressos. Handcrafted sodas like bush tonic and wattle form the basis of the imaginative refreshments at PS40 (2/40 King St; ps-soda.com), while its black and white interiors recall an Ettore Sottsass vessel. Meanwhile, Beta Bar (238 Castlereagh St, betabarsydney.com.au) is an elegant lounge with luscious libations, Greek-style mezze snacks and remarkable glassware.
