what is the difference between hamburger and burger
Hamburger A hamburger, beefburger or burger is a sandwich consisting of one or more cooked patties of ground meat, usually beef, placed inside a sliced bread roll or bun. The patty may be pan fried, barbecued, or flame broiled. Hamburgers are often served with cheese, lettuce, tomato, bacon, onion, pickles, or chiles; condiments such as mustard, mayonnaise, ketchup, relish, or "special sauce"; and are frequently placed on sesame seed buns. A hamburger topped with cheese is called a cheeseburger.
McDonald's The United Kingdom and Ireland business model is different from the U.S, in that fewer than 30 percent of restaurants are franchised, with the majority under the ownership of the company. McDonald's trains its franchisees and management at Hamburger University in Oak Brook, Illinois.[29][30] In other countries, McDonald's restaurants are operated by joint ventures of McDonald's Corporation and other, local entities or governments.[31]
