Xian's Muslim Quarter is a fascinating place. Located in the heart of the city, pedestrians pour into the streets every night to buy food and to people-watch. Some vendors shout to get your attention, others blast music from outdoor speakers. Not many cars brave the streets, but plenty of rickshaws and motorcycles force their way through the crowds, honking their horns the entire time. It's a loud and brash environment, and the energy is intoxicating. Most tourists only come to Xian to see the Terracotta Warriors, but you should also take some time to walk through the Muslim Quarter.
