1. San Francisco, CA
One of the oldest and most established Chinatowns in the United States (it was established way back in 1848), SF's Chinatown is full of culture and attractions, from arts organizations like the Chinese Cultural Center and the annual Chinese New Year festival to the famous Golden Gate Fortune Cookie Factory and modern watering holes like China Live. It's also one of the most walkable (read: flattest) neighborhoods in a city filled with hills. Start at the Dragon Gate, then peruse Grant Avenue, the neighborhood’s main thoroughfare, for just a taste of the varied shops, bakeries, bars and restaurants you can find here.
