It's been open for only a year, but the Kentucky Fried Chicken outlet in Beijing already is the fast-food chain's biggest seller.

The Louisville-based company announced Sunday that of its 7,700 restaurants around the world, the Beijing outlet, which opened officially on Nov. 12, 1987, has registered one-year sales equivalent to about $3 million."Chinese consumers have embraced Kentucky Fried Chicken with tremendous enthusiasm," said Richard Mayer, KFC chairman and chief executive officer. "We believe Beijing will prove to be an excellent model for additional KFC joint ventures in China."

The 12,000-square-foot restaurant, which accepts both local currency and foreign exchange certificates, is the largest in the Kentucky Fried Chicken system, seating 510.

Menu items include KFC's original-recipe chicken, cole slaw, mashed potatoes and gravy, desserts and Pepsi-Cola soft drinks.

Two additional Kentucky Fried Chicken restaurants are scheduled to open in Beijing this year, and further plans are under way for 1989. The chain also has announced plans to build KFC restaurants in Shanghai.
