De 9 Straatjes Health & Beauty

This teeny offshoot of The City Street Spa offers a slimmed down version of the treatment menu: manicures, pedicures, and brow shaping—that's it. The most brilliant part of all is that they're devoted to walk-ins, meaning you can pop in for a quickie mani/pedi on a whim while wandering around Nine Streets.

The purpose of The City Street spa is to provide all the services one might look for in a traditional spa, but in an urban setting with busy schedules in mind. The treatment menu includes massages, facials, waxing, eyebrow shaping, and mani/pedis—all performed in a tranquil, minimalist environment. For the guys, there's face-mapping, manicures, and pedicures. There's a mini spa outpost a few blocks away that's really good about walk-ins.
