"With a nod to the significant landmark building where it makes its home, Poste Moderne Brasserie is also a testament to exquisite foods, prepared amid a backdrop of United States history. Set in the original 1841 General Post Office, Poste has become a modern-day favorite dining destination of local foodies and a leader in sustainable and eco-friendly practices."
