Lee's Chinese 1970's and 80's The Best!

We ran a Liquor store on Clark and Sheffield back in the 1970's and 80's There was a restaurant called Lee's across the street at c3410 N Clark (later became Mongolian House with new owners). Lee was Korean, and he introduced Schezuan and Hunan when all anyone new was Cantonese. He later opened a modern designed place on the second floor at 1750 N Clark above Bigsby and Kruthers. He made the best Kung Pao Shrimp, Spicy Chicken Wings, Mongolian Beef and Lamb. His Hot and Sour Soup was also exceptional. We used to see him Boogying at Rush street after his place closed at night. We lost track of him and wonder what happened to him. We would love to contact him which I know is a long long shot. Thanks
