Learn French: Le menu est parfait, merci. - The set menu is perfect, thank you.

In a French restaurant, le menu usually refers to a fixed-price meal with specific choices (like a starter, main, and dessert). If you want the full list of everything the restaurant serves, you ask for la carte.

Is parfait an adjective here? Does it change depending on the noun?

Yes! Parfait is an adjective meaning 'perfect'. Because le menu is a masculine word, we use the masculine form parfait. If you were talking about a feminine word, like la soupe (the soup), you would add an -e and say la soupe est parfaite.

How does this fit into a lesson about Je voudrais?

This is a great follow-up sentence! If you just ordered by saying Je voudrais le menu (I would like the set menu) and the waiter explains what it comes with, you can reply with Le menu est parfait, merci to politely confirm your choice.

Can I say C'est parfait instead of Le menu est parfait?

Yes, C'est parfait (It is perfect) is a very common and natural way to accept a suggestion in a French restaurant. Using Le menu est parfait is just a slightly more specific way to confirm exactly what you are happy with.
