One of our favorite neighborhoods in the world is SoHo in New York City. The once industrial neighborhood turned vacant neighborhood turned arts district turned trendy boutique heaven is one of the coolest spots in New York’s five boroughs. Yes, it is filled with awesome shopping, great restaurants and trendy hotels. But to me, the main drawing card is all the awesome SoHo architecture thanks to the best collection of cast-iron architecture anywhere in the world. Well, that and all the shopping really makes my wife happy.
