Baku, sometimes spelled as Baki or Bakou, is the capital, largest city, and largest port of Azerbaijan and the Caucasus region. It is located on the southern shore of the Absheron Peninsula, that projects into the Caspian Sea. The city consists of two principal parts: the downtown and the old Inner City (21.5 ha).
The national drink is chay (tea), which is drunk Turkish-style from small tulip-shaped glasses. It is normally taken with sugar but no milk.
