From the bold, red buildings lining the street to a well-curated mix of restaurants, cafes and shops, Chiltern Street epitomizes "London cool" (whatever that might mean). This is a great alternative to and escape from the insanely packed Oxford Street. Grab a coffee at Monocle Cafe and indulge in some retail therapy at Sunspel, TRUNK and Cire Trudon. If you're lucky enough, grab a dinner reservation at Chiltern Firehouse to cap off the day. LINK.
