The Café at the Museum will overlook the The Royal and Ancient Clubhouse, the first tee of St Andrews' famous Old Course and the West Sands beach.
Serving locally sourced Scottish fare, the venue will have 78 covers indoors, 60 on its adjoining outdoor terrace and will be available for private hire for receptions of more than 100 guests.
The British Golf Museum's refurbishment marks 25 years since it first opened and includes a remodelled reception and galleries.
Angela Howe, museum & heritage director, said: "The café, the re-designed galleries and shop herald a new chapter in the Museum's history and we are excited by the direction we are going in. The building has been transformed from a semi-hidden bunker to an elegant addition to the landscape. It has a stronger presence, which we hope will appeal to visitors and the local community."
The Café at the Museum will be run by Ampersand Catering, whose portfolio includes the Palace of Holyrood House, London Zoo and Kensington Palace.
