When Buoy Lee, owner and founder of the Hong Kong Chinese restaurant, first walked by the property on 1238 Mass. Ave. in 1954, she could sense its potential. “I thought to myself—jeez, that place has feng shui,” Lee said. This week, as the Kong, as the restaurant is affectionately known among students, prepares to celebrate its 60th anniversary, Lee and her family reflected on the growth of the business and its landmark status in Harvard Square.
