The Cavalry Bar provides a welcoming atmosphere in which to relax or socialise with friends, family and colleagues. An extensive bar menu includes a wide selection of beers, wines and spirits, including Guy Cadel Champagne served by the glass, or a warming Inverarity ten year old single malt whisky (bottled especially for The Rubens in Speyside, Scotland).
Interesting military artefacts are dotted around the bar area, recalling key historical events throughout the British Empire. In the evenings, a pianist provides soothing background music. The Palace Lounge, adjoining the bar, is a magnificent bright open space with panoramic views of The Royal Mews at Buckingham Palace, the Queen's stables.
