Translation of "high-end" into Italian

The lunch at the high end restaurant named Cerrutti included white truffles, expensive champagne, and other delicacies.

Il pranzo al Cerrutti, ristorante di lusso, includeva tartufi bianchi, champagne costoso e altre prelibatezze.

But word on the street is this shipment was loaded with high end jewels they didn't take.

Ma si dice che il carico contenesse anche gioielli esclusivi che non hanno rubato.
