Vada Spa. End of story.
I think that every college student should have a mandatory "spa" day. Today, I went with a few of my classmates to Vada Spa on Waverly and 6th Avenue, for some relaxation treatment--sponsored by the cohort program at Stern (I only paid 7 dollars!). No matter what, Vada Spa an inexpensive way to rejuvenate after a stressful week of work, whether it be with a manicure&pedicure, or an "out to lunch" facial.
Cute little beauty salon.
Manicure Stations (they have an upstairs too!).
