This bar has in-house soda works. It's by bartenders Michael Chiem (ex-Lobo Plantation) and Thor Bergquist (ex-Bulletin Place).

Bergquist dabbled in soda making while bartending in New York. When he returned to Sydney he was keen to start his own operation. He supplied. drinks to venues such as Archie Rose, Firedoor and Bennelong.

PS40 has a bright, high-ceilinged interior dominated by bold swathes of black and white. Custom-built stools and tables rest alongside elegant windows facing the bustle of King Street. The soda-making plant sits on a raised platform opposite the long bar.

The bar's taps pour PS Soda's core range – wattle cola; bush tonic; smoked lemonade; and blackstrap ginger – plus a seasonal flavour. There is also beer from Young Henrys and Wayward Brewing. Lo-Fi Wines put together a wine list of around 35 bottles. It’s focus is on organic wines from small producers.

A 10-drink cocktail list will change regularly. Think the Batanga, a mix of wattle cola, green coffee bean-infused tequila, lime and smoked salt. The sodas also come with suggested serves. Such as a really good Cuba Libre or a Dark and Stormy.

The menu’s focus is on snacks designed to complement the cocktails. There are pickles, terrines, pates, charcuterie and a bahn mi.
