 The Library Restaurant is an upscale steakhouse and elegant private events space in a historic building where 7 presidents have dined since 1887. The private room at the Library is one of the North East's most beautiful dining experiences. Our home is in the grand and historic Rockingham House, steps from the center of Portsmouth, and our dining rooms boast an original vaulted mahogany ceiling, three crackling fireplaces, a martini lounge, and a beautiful private dining space under an ornate original painted ceiling fresco, perfect for celebrations.
