In the United States, a restaurant that specializes in beef steaks is a steakhouse. The more expensive steakhouses serve the highest grades of beef and often dry age it for many weeks. The well-aged beef cooked on high-heat grills and broilers produces a steak difficult to emulate in a home kitchen. A typical steak dinner consists of a steak, optionally topped with sautéed onions or mushrooms, with a starchy side dish; usually baked or mashed potatoes, or thick cut fried potatoes known as steak fries. Chili, rice, pasta, or beans are also common sides. A side salad or a small serving of cooked vegetables often accompanies the meat and side, with corn on the cob, green beans, creamed spinach, asparagus, tomatoes, mushrooms, peas, and onion rings being popular. Bread is generally served, usually a dinner roll.
