Park St. Diner was created by the team behind The Grounds of Alexandria, The Grounds of The City, and The Grounds Coffee Factory, bringing years of experience in crafting memorable dining destinations to the heart of Sydney. Inspired by classic American diners, comfort food, and The Grounds’ signature flair, the diner was built to offer all-day dining that’s effortless, fun, and full of flavour.

From breakfast favourites to relaxed lunches, and cocktails or drinks at the bar late into the evening, every detail - from the retro-inspired décor to pops of colour and friendly service - reflect the team’s love of good food, great company, and lively, welcoming spaces. With both dine-in and takeaway available, it’s a place to enjoy a meal, a coffee, or a drink - just steps from the Gadigal metro station and Sydney’s Town Hall, St. James, and Museum train stations.
