In the 1600s, the history of Bond Street started with just one mansion, built by the Earl of Clarendon. He sold the property (and what was left of the house after the Great Fire), and three people set about to make it a successful housing district. However, they went for the more profitable approach--renting out smaller properties on a constructed road. They managed to do that, and the original Bond Street (referred to now as "Old Bond Street") was created. By 1720, Bond Street connected Piccadilly and Oxford Street. Expensive shops began to be frequented by expensive people to show how notable and important and beautiful they were. A notable man in the 1800s, named Beau Brummell spent eight hundred pounds a year on clothing, much of it on Bond Street. Sotheby's came to Bond Street in 1917. In short, Bond Street has been (and continues to be, as will be discussed in the next paragraph) the place that all fashionable people shopped for hundreds of years. 

Today, the street remains a spectacle of expensive shops. Tiffany's, Burberry, Prada, Chanel, and many, many more designers are all placed in the same row of buildings. Sotheby's remains, as well. Socialites and celebrites parade the streets, much like the street from three hundred years ago. One can still see the divide between Old Bond Street and New Bond Street. Many of the stores are incredibly old as well. Burlington Arcade, full of luxury jewelry stores, was built in the 1800s. Asprey has been around since the 1830s. Fenwck has been around since the 1890s. All of these stores would have been on Bond Street in Mrs. Dalloway's time and are still standing, albeit selling more modern goods. Luxury restaurants and hotels are on the street as well (I'm sure you've heard of Claridge's!) and The Royal Academy of Arts. It basically sounds like a wonderful day out, shopping and eating!
