Nigeria is a federal republic modeled after the United States, with executive power exercised by the president. The government of Nigeria is also influenced by the Westminster System model in the composition and management of the upper and lower houses of a bicameral legislature.
Lagos, Abuja and other major cities have a big selection of restaurants, serving everything from traditional Nigerian dishes to French baguettes, excellent sushi and good hamburgers. In short, European, North American and Asian tastes are well catered for, and you'll also find a range of different cuisines from across the African continent.
Religious affiliation in Nigeria is strongly related to ethnicity, with rather distinct regional divisions between ethnic groups. The northern states, dominated by the Hausa and Fulani groups, are predominantly Muslim while the southern ethnic groups have a large number of Christians. In the southwest, there is no predominant religion.
