Spring is taking its time this year, delaying the sensory pleasures of the season: green leaves, blooming daffodils, sun-warmed lunch hours. There is one sense you can satisfy though: smell. Start with the grapefruit and vodka pedicure at Sweet Lily ($62: 222 W. Broadway, nr. Franklin St.: 212-925-5441), an hour of beautifully scented toe pampering. Your Feet are bathed in warm grapefruit juice, which aids in exfoliation, and vodka, an antiseptic. (If you have small cuts on your feet or legs, you’ll feel the sting.) A traditional file is used to slough rough calluses, followed by another round using a fragrant lime half dipped into a sugar scrub. Naturally, nails and cuticles are buffed and filed to perfection.
