It's not often you see your dry cleaner at the opera and she gives you a kiss and a hug. But Kim Coe is not your average dry cleaner. She is a stain-removing savant. And although she's not the cheapest in town, she's worth every penny. Her small store on Biscayne Boulevard handles dry cleaning for several South Beach hotels and even Miami City Ballet. But she will just as happily hand-finish your suit ($14.50), pants ($6.75), or shirt or blouse ($6.25). She even does alterations. But the real reason we keep going back to Kim is that she's like the aunt we never had. When Coe arrived in the United States from South Korea just before Christmas 1970, she had nothing but her daughter and $10. Walk into her store today and you'll see a woman at home in her self-made empire, right down to her dog Sparky and the Girl Scout cookies she sells on behalf of neighborhood kids.
