In 1974, Margaret Kuo opened the Peking in the Granite Run Mall as the Philadelphia area's first Chinese restaurant serving authentic northern Chineses cuisine.

Since its debut, the Peking has received numerous outstanding reviews and awards for its electable cusine and elegant yet understated decor. Madam Kuo's adherence to heritage and tradition enables her to refine her cuisine over the years without compromising its authenticity. That Madam Kuo subsequently incorporated Kansai style Japanese cuisine in her culinary repetoire only helped establish the Peking as the preeminent East Asian Restaurant in the Delaware Valley.
