Wide and Narrow Alley (宽窄巷子)
This is a top tourist attraction and a must-see if you are visiting Chengdu. As the name suggests, it is composed of two alleys, one wide and one narrow. It's very easy to access and you won't break your wallet spending a night there. Besides street foods and fancy restaurants, there are shops that offer traditional Chinese opera performances and face changing shows. If you are pressed for time, pick a restaurant that also has a similar albeit smaller performance.
Ear cleaning service
If you dare, you can get your ears cleaned by some of the professional ear cleaners in the alley. The health benefit of clearing your ear wax is questionable and to have such a delicate operation out in the open is a bit scary.
