Georgian cuisine and wine have evolved through the centuries, adapting traditions in each era. One of the most unusual traditions of dining is supra, or ''Georgian table'', which is also a way of socializing with friends and family. The head of ''supra'' is known as tamada. He also conducts the highly philosophical toasts, and makes sure that everyone is enjoying themselves. Various historical regions of Georgia are known for their particular dishes: for example, khinkali (meat dumplings), from eastern mountainous Georgia, and khachapuri, mainly from Imereti, Samegrelo and Adjara.
