French to English Other Cooking / Culinary menu

Having had my brain scrambled by an esoteric job on art history, I'm having trouble finding the right phrase for this. I'm translating various menus for a restaurant, one of which is the Menu de Fin d'Année. Each course has three choices. Underneath it says:

Uniquement sur réservation.
Un choix unique par table
Budget : xx€ / personne.

Possibilité de choix multiples
Budget : xxx€ / personne.

Confirmation des choix 3 jours à l’avance par mail à : ...

So two options: either everyone at the same table eats the same menu, or they choose different items at a slightly higher cost per head. I feel there must be some sort of standard phrase for this but can't track it down.

Incidentally, I had something like this before with the client's general menu, where the phrase used was "Gamme de Menu identique par table. A partir de 10 personnes.", which I translated as "For groups of 10 people and more, we ask that the whole table orders the same menu" but something more concise is needed here.
