Define the main features of an à la carte menu.

An à la carte menu is a type of menu found in restaurants which allows customers to order individual dishes from a menu in a restaurant, as opposed to table d'hôte, where a set menu is offered. Here are the main features of an à la carte menu:

1. Variety of Options: An à la carte menu offers a wide range of dishes. This includes starters, main courses, desserts, and side dishes. Each category has multiple dishes to choose from.

2. Individual Pricing: Each item on an à la carte menu is priced separately. This means that the price you pay is determined by what you order. This is different from a set menu, where a series of dishes are offered for a fixed price.

3. Flexibility: An à la carte menu allows customers to mix and match dishes according to their preferences. They are not bound by a predetermined set of dishes.

4. Quality: Since customers are paying for each individual dish, there is often an expectation of high quality and presentation for each dish.

5. Time: Ordering from an à la carte menu may take more time than ordering from a set menu, as each dish is prepared to order.

6. Cost: While an à la carte menu offers more flexibility, it can also be more expensive than a set menu, as each dish is priced individually.
