From the moment we laid eyes on Ji Baek, the 30-year-old Korean style vixen-cum-nail guru, we knew her venture, Rescue Aromatherapy Nail Salon, would be a hit.Which meant lines, wait lists, and a very, er, high-maintenance clientele…But her charming nook in SoHo was so cool we deal. So we did. How could we resist the antique manicure tables, private pedicure alcoves, cozy tin-ceiling feel … not to mention leaving with a cutely embellished big toe done up with tiger stripes, ladybugs, or dainty petals?To handle such mass demand, Rescue’s second outpost opens this week. A bigger, sleeker version of the original, Rescue Beauty Lounge will offer not only Ji’s trademark manicures, pedicures, and waxing services but makeup applications, hairstyling (come fall), and a killer arsenal of hard-to-find products (like Wantosa, a cult line from Japan).The spot opens Thursday, but appointments are being taken now. Skip the hype, make your appointment, and ask for the DailyCandy pedicure. Heck, if you can’t eat it, you may as well look at it.
