I loved the Old Quarter. Each street's name corresponds to the wares in its shops. It was mind-boggling that the Vietnamese would be so rigid & organized, which is not the first impression you have (or even the 10th) when you visit this country. Hang Quat is, of course, the Street of Fans. It wasn't any more or less charming than the other streets, but devoting a whole block to the sale of fans is just a tad more unexpected than Street of Silk.
