Washington, D.C., is rich in fine and casual dining; some consider it among the country's best cities for dining. The city has a diverse range of restaurants, including a wide variety of international cuisines. The city's Chinatown, for example, has more than a dozen Chinese-style restaurants. The city also has many Middle Eastern, European, African, Asian, and Latin American cuisine options. D.C. is known as one of the best cities in the world for Ethiopian cuisine, due largely to Ethiopian immigrants who arrived in the 20th century. A part of the Shaw neighborhood in central D.C. is known as "Little Ethiopia" and has a high concentration of Ethiopian restaurants and shops. The diversity of cuisine is also reflected in the city's many food trucks, which are particularly heavily concentrated along the National Mall, which has few other dining options.
