Final answer:
Typically, the dressing for a side salad that comes with an entree is chosen by the guest. A variety of dressings are offered, and the server should ask for the guest's preference or suggest the default option that pairs with the entree.
Step-by-step explanation:
When a guest orders an entree that comes with a side salad, the type of dressing to be served with it typically depends on the guest's personal preference. Many restaurants will offer a selection of dressings for the guest to choose from, such as ranch, vinaigrette, blue cheese, or Caesar. The server should ask the guest which dressing they would like, or if the menu specifies a particular dressing that pairs with the entree, the server can suggest that as the default option but still confirm with the guest.
