The unique features of an à la carte menu are that it offers individual prices and many choices. In an à la carte menu, each dish is priced separately, unlike a fixed price menu where the dishes are sold as a package deal. Additionally, à la carte menus offer a wide variety of choices, allowing diners to select and pay for only the dishes they wish to eat. This makes à la carte menus more flexible and customizable, as diners can tailor their meals to their personal preferences and budgets.
