The press release explains it well enough:

Brookfield Place has signed a 10-year, 2,748 square-foot lease with Clean Market, a popular modern wellness hub. Set to open in Fall 2019 at Brookfield Place’s 230 Vesey Street Shops, Clean Market’s second New York City location comes on the heels of a successful grand opening in Midtown last year. The new location, centrally located just off the Winter Garden stairs and across from Hudson Eats, will offer the full suite of Clean Market services, including a Vitamin IV Drip Lounge, full-spectrum infrared saunas, whole-body cryotherapy, and a functional food and tonic bar with a Vitality Supplement Market, all under one roof. Upon opening, Clean Market will be the lone all-in-one store in the Financial District with these unique health and wellness offerings.

And this is from founder Lily Kunin (pictured above):

You may know me from my blog @cleanfooddirtycity, where I’ve created healthy and easy recipes for a few years. I enjoyed sharing my food with people on social and through my cookbook, but had always wanted to create a destination that allowed people to taste, see, and experience healthy food and a functional approach to wellness. One day, with the help of partners + mentors, I decided to make my idea of a haven in the middle of Manhattan a reality.

And here are some shots of the Midtown location….
