No less important and convenient is the fact that a prepaid deposit can be adapted respectively. If the guests know ahead of time that they will be choosing the tasting menu, the restaurant can set the advanced full-price payment, or take a deposit. If they’re choosing the à la carte dinner, why not make an advanced payment of $20pp, which can later be applied to the final bill?
Regular reservations might be accepted without any ticketing too, but implementing deposits and prepayments for special occasions and events is hugely convenient. No empty tables or lost revenue during a special concert, once-in-a-season tasting menu, New Year’s Eve party, or Valentine’s day!
