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.
In-N-Out Burger In-N-Out's first location was opened in the Los Angeles suburb of Baldwin Park, California in 1948 by the Snyders[6] at the southwest corner of what is now the intersection of Interstate 10 and Francisquito Avenue. The restaurant was the first drive-thru hamburger stand in California, allowing drivers to place orders via a two-way speaker system.[6] This was a new and unique idea, since in post-World War II California, carhops were used to take orders and serve food.[14]
