Having opened in 1948, In-N-Out burger has had many years to perfect the art of fast food burger making. As opposed to other fast food restaurants, In-N-Out prides itself on never freezing, pre-packaging, or over-processing their ingredients. In fact, not a single In-N-Out branch even contains a microwave, heat lamp, or freezer. The burgers they use are 100% pure beef free of additives, fillers, and preservatives – which they can guarantee since they own and operate their own patty-making facilities. With a style that’s become almost iconic, there is no question that In-N-Out is the place to be if you are looking for a delicious meal on the go.
