Shall we book a special dinner to celebrate?
'Festeggiare' = fe-steg-GIA-re. 'Speciale' = spe-CIA-le.
Use this to mark an occasion with an elevated dining experience. Suggesting a 'special dinner' implies something above the ordinary — a restaurant rather than home cooking, and a celebratory purpose. It shows care in wanting to mark the moment.
'Cena speciale' (special dinner) — the adjective 'speciale' follows the noun in Italian. 'Per festeggiare' (to celebrate) — 'per' + infinitive expresses purpose. 'Prenotare una cena' (to book a dinner) is the standard Italian expression.
Andiamo in un ristorante stellato per l'occasione?
Shall we go to a starred restaurant for the occasion?

Framing the dinner as something owed to them
Italian celebrations ('festeggiamenti') are always centred on a meal. A promotion, graduation, birthday, or anniversary demands a 'bella cena' (fine dinner). Italian gastronomy at the high end is extraordinary — Italy has more Michelin-starred restaurants than any country except France. Celebrating with a fine meal is the Italian way of honouring an achievement.
