Gia's Instagram account describes it as a "rustic and fun Italian restaurant." No word on an opening date. (As you can see on the storefront pic above, they are still hiring for all positions.) You can sign up for updates on the Gia website.
Gia Trattoria at this address for a brief time in 2015.
Actually, there were a lot of places here for a brief time between November 2014 and June 2015 ... this is when the storefront was divided into two spaces, and Forcella, Espoleta, Gia Trattoria, Slice of Naples, SRO and Bowery Pizza came and went over a six-month period.
