Nick's Seafood Restaurant, Cockle Bay Wharf. Sydney’s best loved seafood restaurant is located on the CBD waterside overlooking Darling Harbor. This 400 plus seated venue includes an internal dining room which extends through to an outdoor deck area on the waterfront promenade. The original interior has been refitted to upgrade the dining, bar, kitchen and back of house areas for a new look and feel which maintains the integrity of the brand. Clean architectural lines combined with natural materials including stone and timber create a enduring relaxed and contemporary dining experience.
