In addition to Boston and the Chinatowns in the New York metropolitan area, several bus companies serve the Chinatowns of Edison, New Jersey; the Cherry Hill Mall; Philadelphia; Washington, D.C.; Baltimore; Atlanta, and the Atlantic City casinos. Buses also serve Ohio, Michigan, Rhode Island, Virginia and Florida, also stopping in smaller, predominately non-Chinese areas in North and South Carolina. On the West Coast, buses link the Chinatowns of the San Francisco Bay Area; Los Angeles Chinatown and the San Gabriel Valley; and Las Vegas' Chinatown and its casinos. Chinatown bus lines enable Chinese immigrants, mainly restaurant workers, to travel inexpensively along the coasts. In total, the buses travel within 24 U.S. states and Canada.
