The signage is up for Montauk Salt Cave, opening soon on the upper level at 90 E. 10th St. between Third Avenue and Fourth Avenue.
Here's more about what they offer via their Facebook page:
Salt therapy is a natural way of healing ailments related to respiratory disease, skin conditions and inflammatory symptoms. You will be surrounded with tons-literally tons of Himalayan salt that is both anti-bacterial and anti-inflammatory. The cave is a beautiful setting for you to come and simply feel better. If you suffer from allergies, asthma, cystic fibrosis, COPD or any respiratory illness...you have found the right place.

The spa has locations in (duh) Montauk as well as Huntington. You can learn more about their business here. Ikinari Steak, where patrons mostly have to eat standing up, is right downstairs. The upstairs space was last leased to Miron Properties.
