(By Johanna Wilson, jwilson@thesunnews.com) Buffet City is a metropolis of Chinese food and other cuisine. It opened two weeks ago at 2711 Beaver Blvd. in Surfside Beach, S.C., and is already a favorite of locals.The buffet has more than 120 items and includes snow crab legs and oysters on the half shell as a part of its dinner buffet at no extra charge - a deal you rarely find elsewhere.
