For a full 13 blocks, Royal Street runs parallel to Bourbon Street, yet this thoroughfare – one of the finest stretches of art galleries, antique stores, wrought iron balconies, restaurants and architecture in the USA – is sometimes almost completely missed by visitors. This is a real shame; beyond the qualities we’ve just described, Royal Street makes a nice counterbalance to the neon and noise of Bourbon.
