what do you call a hamburger without a bun
Hamburger The term "burger" can also be applied to the meat patty on its own, especially in the UK where the term "patty" is rarely used, or the term can even refer simply to ground beef. The term may be prefixed with the type of meat or meat substitute used, as in "turkey burger", "bison burger", or "veggie burger".
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]
