The Library Restaurant

The Restaurant

The Library Restaurant occupies the ground floor of the Rockingham House, a Federal-period mansion at 401 State Street that was built in 1785 as the residence of a New Hampshire chief justice and later operated as the Rockingham Hotel - a hotel that hosted Daniel Webster, Theodore Roosevelt, and the Portsmouth Peace Treaty delegations of 1905. The restaurant has been in continuous operation in the building since 1976 and is structured as a series of intimate wood-panelled rooms - the main dining room with floor-to-ceiling mahogany bookshelves and original 18th-century built-ins, a smaller Madison Room for private dining of up to twelve, and a clubby corner bar with leather wing-back chairs in front of a working marble fireplace.

The kitchen is openly classical American steakhouse - Certified Angus Beef from a Midwest producer, hand-cut and aged in-house, charcoal-grilled over a hardwood-fired flat-top. The bone-in ribeye, the porterhouse for two, and the filet Oscar are the room's signatures. Sides are served family-style and a few have followings of their own: bourbon-creamed corn with chipotle butter, lobster macaroni-and-cheese under a brown-butter breadcrumb crust, asparagus with bearnaise, twice-baked potato with smoked Vermont cheddar. The off-menu programme has a beef Wellington that requires twenty-four-hour advance notice and is consistently considered the best version on the Seacoast.

The wine list runs about 320 references with serious vertical depth in Napa Cabernet Sauvignon (multiple Stags Leap, Caymus, Silver Oak verticals), Bordeaux (a focused left-bank section), and Brunello, plus a thoughtful by-the-glass programme that allows a table to taste five different California Cabernets over an evening. Service is captain-led at the international hotel level - the floor team includes several senior staff with decades at the restaurant, and the pacing is unhurried at three hours for a full dinner. After the meal, the Rockingham House bar with its fireplace and bookshelves is the most clubby late-evening room in the city.
