Cliveden House & Pavilion Spa, Taplow, Berkshire SL6 0JF, UK
An intimate, sultry underground cave, the Cellar Dining Room is perfect for a more informal setting. Its brick walls, mighty pillars and vaulted ceilings highlight its stake in history. It was once Lord Astor's private wine cellar, making it ideal for wine tasting. It has been lovingly restored, remaining an unusual and atmospheric function room for smaller parties and private gatherings.
