Juvenex

Juvenex spa, tucked away in an office building in the center of Koreatown, is open 24/7. It's ladies-only during the day, but the spa becomes coed in the evening, making it a popular late-night spot for Broadway actors and dancers winding down after a performance. Standard spa treatments—including facials, massages and body wraps—are offered, but regulars praise the Japanese-style soaking ponds, infused with ginseng, sake and algae.
