How would you refer to the range of different dishes available at a restaurant?

The term "variety" refers specifically to the range of different types of dishes or options available, which perfectly encapsulates the idea of having multiple choices. It emphasizes the presence of various kinds or forms within the offerings, suggesting a rich assortment that caters to different tastes and preferences in a restaurant setting.

While "selection" and "menu" could also relate to this context, "selection" usually implies a choice among a more limited set of options, and "menu" specifically refers to the list or presentation of those dishes, rather than the concept of having multiple types available. "Diversity" tends to connote differences among groups rather than just a range of choices, which makes "variety" the most fitting term for describing the assortment of dishes at a restaurant.
