When in the Western United States it is highly recommended to enjoy the strict simplicity of IN-N-OUT BURGER. The drive-through burger restaurant’s menu remains the same as when the first IN-N-OUT was opened in Baldwin Park, California, in 1948: three burger varieties – hamburger, cheeseburger and ‘double-double’, which is double meat and double cheese – French fries, fountain drinks and precisely three flavours of milkshakes. Although, the chain has a not-so-secret by request menu that includes another American favourite, the grilled cheese sandwich. The charm of IN-N-OUT, besides the jolly packaging is the fast food chain’s atypical commitment to freshness. Restaurants do not contain a microwave, heat lamp or freezer. It results in an incredibly tasty burger.
