According to ACRIS, Pret a Manger's parent company has an interest in 400 Park.
The adjacent building, 410 Park, is owned by a UK company, Global Holdings Management. Interestingly, Pret's parent is also a UK-based corporation. Perhaps, there's a connection.

I suspect that SL Green knows something about this.
