August is traditionally the holiday month.  Commercial life in London  can be quieter than usual, but the gap is filled by  visitors.   In King’s Road, Chelsea it is business as usual.  Never more so than here. at Bourbon Hanby  Arcade opposite Chelsea Old Town Hall.  Regular customers may be on holiday but new faces take their place.  Looking at the wide range of dealers’  stock they  find something  to take home.    Join them.    The Arcade is open every day Monday to Saturday from 10am to 6pm.
