You must ascend an extra-long escalator to get to Jing Fong’s massive second-floor dining room where each pink tablecloth is so bright that you’ll be reaching for your shades. In the mornings, Jing Fong’s specialty, dim sum, is served from wheeled carts by waiters in spiffy yellow jackets. During weekends the restaurant gets so busily chaotic that you might have to chase down the steamed dumpling or egg roll of your choice.
