Diner food refers to a variety of classic American dishes typically served in diners, which are casual restaurants open throughout the day and night. Common items include burgers, fries, breakfast foods like pancakes and omelets, and comfort foods such as meatloaf and macaroni and cheese. Diners often emphasize hearty portions and quick service. The atmosphere of a diner is usually relaxed and nostalgic, often featuring a retro design with booths and a counter. Many diners also offer a selection of desserts, including milkshakes and pies, making them popular spots for families and late-night diners alike.
