For shopping, I think you can do them all in Guangzhou. There is a Zhongda Fabric Market for textile, accesories can be found in Haizhu Square area. For electronic, I think Shenzhen is usually the supreme choice. You can taste Chaozhou dish which is also an important branch of Canton Cuisine. As to turkish restaurant, I am afraid no. Guangzhou have some: Ottoman Turkish Restauran in Huanshi Donglu. There is also a turkish barbecue in Donghai Mansion.
