Unpolished and unkempt talons, essential for beaming secret messages back up to the mothership, are the easiest way to identify an alien. Avoid accidental CIA quarantine with today's Groupon: for $35, you get a High Rollin' manicure and pedicure at Martini Nails & Spa, a $70 value.

Buttery leather chairs, super clean stations, and soothing simulated-nature décor make the salon a relaxingly exotic locale for refreshing fingers and toes. As the name implies, the High Rollin' treatments are a kick up from the standard polish and paint. Digits are treated to the requisite shaping and smoothing, followed by a cuticle grooming, cleaning, sugar scrub, callus treatment, foot mask, and hot-stone massage. Hands are then encased in a toasty terrycloth before an expert aesthetician liberally coats nails in the color of your choice.

Artichoke-green walls, colorful lights, and a friendly staff transform the modest storefront salon into a tropical oasis. Martini Nails prides itself on superior customer service, with special attention to nail chips and nicks, and it features the Opi-Axxium Gel System. Like Thanksgiving dinner at Grandma's, walk-ins are welcome, but calling ahead to reserve a spot is suggested.
