What is included with the sandwiches served at the restaurant?

Kettle chips are often included with sandwiches at many restaurants due to their crunchy texture and flavor, which complement the softness of the bread and filling. They provide a satisfying contrast and are a convenient side option that can be easily served alongside a sandwich without additional preparation. The choice of kettle chips can also reflect a casual dining experience, aligning with the rustic and snack-like attributes that many diners enjoy with their sandwiches.

Other options such as French fries, potato salad, or fruit salad may not consistently accompany sandwiches in a variety of restaurants. French fries generally require frying and can be heavier, while potato salad and fruit salad may not have the same widespread appeal or pairing suitability with every type of sandwich. Kettle chips, however, are versatile and broadly accepted as a classic side, making them a popular choice.
