Extra Hamburger Meat

The item you're referring to is typically known as "extra hamburger meat" or "additional hamburger patties" in restaurants across the United States. Essentially, it refers to additional portions of ground beef that are formed into patties and can be added to a hamburger order.

When ordering a hamburger at a restaurant, customers often have the option to customize their meal by adding extra toppings, cheeses, or condiments. One common customization is to add an additional hamburger patty or two to the sandwich. This can be done to create a larger, more substantial burger, or to satisfy a bigger appetite.

Extra hamburger meat is usually priced separately from the base hamburger and may come with an additional charge. The price can vary depending on the restaurant and the size of the additional patty.

It's worth noting that some restaurants may use different terminology or have slightly different procedures for adding extra hamburger meat to a sandwich. For example, some restaurants may use the term "double patty" or "triple patty" to refer to burgers with two or three patties, respectively.

In any case, if you're unsure about the options or terminology used at a particular restaurant, don't hesitate to ask your server for clarification. They should be able to help you customize your order to your liking.
