If you are in Suzhou and want to eat the local specialty for lunch, I recommend Tongdexing Noodle Shop, which I believe is a chain with multiple locations. We ate at the shop at 13 Gunxiufang roughly 200 meters northwest of Master of the Nets garden (the location shown on Google maps is reasonably accurate). I've attached a photo of the front entrance to help you get there. You can choose either white or red noodles and combined them with various toppings (e.g., pork, fish, eel). The food was very good and inexpensive, but you will need someone in your group who speaks Chinese as the service staff speaks little or no English.
