Anyone who's ever ridden in a cab with me knows that I'm a stickler for good customer service. (I.e., if a driver is incompetent I get real annoyed.) I'm like this about pretty much everything, from restaurants to department stores. (No one--I mean no one--who works at Uniqlo knows where anything is. Unless they've been promoted to the +J department. There, I've noticed, you can't be lazy. But I digress.) Because of my high standards, I never really stick to one place for beauty treatments, particularly manicures, pedicures, and Brazilians. To me, all nail salons are pretty much the same. The people are nice, but you can't put a tip on a credit card and it's rare to find a technician with whom you're so impressed that you make an effort to go see her every week or two. I was fine bouncing along, getting a manicure whenever I had the time. Until, that is, I discovered Tenoverten, a light-filled loft in New York's TriBeCa neighborhood.
