This might just be one of the Capitol's most well-known dining rooms, housed at the corner of Lafayette Square and just a stone’s throw from the White House lawn. Furthermore, it has been reimagined as a blast of color, with blue walls, gold-patterned banquettes and vibrant artwork. The space hums with guests gathered around linen-robed tables.The menu is loosely French but with a number of detours, from steak tartare and Rohan duck breast to black truffle risotto and Maine lobster with pineapple. The Ora King salmon coulibiac is a signature for good reason—featuring layers of mushroom duxelles and herbed rice wrapped in puff pastry and served with sauce mousseline. If soufflé is on the menu, order it.
