A burger restaurant is a dining establishment that specializes in serving burgers, which are typically made of ground meat, often beef, placed inside a sliced bun. These restaurants may offer a variety of burger styles, toppings, and sides, such as fries or onion rings. Many burger restaurants also provide options for vegetarian or vegan burgers to cater to different dietary preferences. In addition to burgers, these restaurants often serve beverages like soft drinks, milkshakes, and sometimes beer. Popular chains like McDonald's and Burger King have made burgers a staple in fast food culture, while many local establishments focus on gourmet or specialty burgers to attract customers.
