The Clubhouse is the social centre of Royal Ascot Golf Club. Whether its a quick coffee before a round, a few at the 19th with a bar meal, or a more substantial meal in the Restaurant, the Clubhouse makes all members and their guests extremely welcome. The two sittings for Sunday Lunch in the Clubhouse Restaurant are always extremely popular.

The Lounge Bar also serves for private functions and is often used for various social events, including Dances, Bridge evenings, Quizzes, and other events organised by the Social Committee, Members or Hired out by other Organisations.

The Clubhouse facilities include Restaurant & Lounge, Lounge Bar, 1887 Golfers Bar, Changing Rooms, Showers, RAGC Club Offices, Meeting Room, Pro Shop & Parking. Smoking is not permitted in the Clubhouse, only on the Patio & Course.

The restaurant is open until 9pm on Wednesday evenings (summer only), serving an 'a la carte' menu.
