Concierge.com's insider take:
The queen's London pied-à-terre is not the most beautiful of palaces, but it's big. Most of the year, all you can do is peer through the iron railings at the guards in busbies—those silly two-foot-tall black fur hats—and check the flagpole to see whether Brenda, as Private Eye calls her, is at home (the standard only flies when she's in residence). But from late July to September, even commoners can enter those gates. The Throne Room, Picture Gallery, Ballroom, and 16 other state rooms are open, as is (a bit of) the south side of the unbelievably huge palace gardens. The Royal Mews, with working stables and display of fancy state vehicles, is just around the corner and also worthy of a visit, as is the Queen's Gallery.
