The new venture launched at the Kings Live Lounge at midday on Saturday, and will showcase craft beers from a Lang Toun business.
The tables and chairs will be set out in the courtyard behind the Live Lounge on the Esplanade - and the team behind it hope it will be a hit with locals and visitors this summer.
Grain Schooner, which is based at Mitchelston Industrial Estate, is provide craft beers, ciders and other drinks, and there will be food from the Tiffin which makes homemade Indian Vegan food.
There will also be acoustic music to help create a chilled summer atmosphere.
The opening day runs until 6:00pm and is open to all to drop in.
Paul Grant, who runs Grain Schooner, is also planning to establish his shop at the Kings as the venue looks ahead to a busy second half of the year.
