It's hard not to feel like a master of the universe when ensconced in this coolly elegant dining room in the imposing shadow of the Capitol. Oversize floral arrangements, tones of blue-gray, a dramatic glass-enclosed wine cellar, and quasi-Danish modern furniture form a backdrop to the contemporary cuisine. Dry-aged rib eye, marinated hanger steak, and porterhouse steak with morel mushrooms are the meaty choices. But brown-butter-drenched tortelloni and poached lobster make a good showing, too, as do sides such as mashed Yukon Golds and Brussels sprouts with pancetta. The crème brûlée trio finishes things off nicely.
