Singapore's diversity of cuisine is touted as a reason to visit the country, due to its combination of convenience, variety, quality, and price. Local food items generally relate to a particular ethnicity – Chinese, Malay and Indian; but the diversity of cuisine has increased further by the hybridisation of different styles (e.g., the Peranakan cuisine, a mix of Chinese and Malay cuisine). In hawker centres, cultural diffusion is exemplified by traditionally Malay hawker stalls also selling Tamil food. Chinese stalls may introduce Malay ingredients, cooking techniques, or entire dishes into their range of catering. Hainanese chicken rice, based on the Hainanese dish Wenchang chicken, is considered Singapore's national dish.
