McDonald"s is the world"s largest chain of fast food restaurants. McDonald"s primarily sells hamburgers, cheeseburgers, chicken products, French fries, breakfast items, soft drinks, milkshakes and desserts. More recently, it has begun to offer salads, wraps and fruit. Many McDonald"s restaurants have included a playground for children and advertising geared toward children, and some have been redesigned in a more "natural" style, with a particular emphasis on comfort: introducing lounge areas and fireplaces, and eliminating hard plastic chairs and tables.

Each McDonald"s restaurant is operated by a franchisee, an affiliate, or the corporation itself. The corporations" revenues come from the rent, royalties and fees paid by the franchisees, as well as sales in company-operated restaurants.

McDonald"s predominantly sells hamburgers, various types of chicken sandwiches and products, French fries, soft drinks, breakfast items, and desserts. In most markets, McDonald"s offers salads and vegetarian items, wraps and other localized fare. This local deviation from the standard menu is a characteristic for which the chain is particularly known, and one which is employed either to abide by regional food taboos.
