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.
As in most of West Africa, Nigeria's climate is characterized by strong latitudinal zones, becoming progressively drier as one moves north from the coast. Rainfall is the key climatic variable, and there is a marked alternation of wet and dry seasons in most areas.
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.
