Pay a call to the beauty giant's spa in Trump Tower; it offers the usual services, but is best known for its world-famous eyebrow guru Eliza Ptrescu. She heads her own division, Eliza's Eyes, staffed with several aestheticians. She's booked a couple of months in advance and charges $100 for a first-time pluck, so plan ahead and save your pennies. Subway: N, R, W to 5th Ave./59th St.
