:up: The 'are' version is definitely wrong. But the 'is' version suggests that you may have an understanding of 'menu' as a description of the on combination that is available.
This sense is accurate in the context of a formal dinner, say. But in a restaurant, the menu is a list of everything that's available. If you want to say that something is avaliable, the expression 'on the menu' is what you want.With 'on the menu' you could use either 'is' or 'are', with different meanings.
