Пармезан is a free iPhone app designed as a loyalty program for customers of specific restaurants. Users can present their mobile guest card during payment to accumulate points with each order, which can be redeemed for delicious gifts, starting with a signature dessert on the next visit. The app enhances the dining experience by rewarding regular customers with incentives.

The app has specific conditions; points do not accumulate with discounts and are not applicable to business lunches at certain restaurant locations. Points are credited within one hour after payment, allowing users to enjoy their rewards quickly. To redeem gifts, customers must inform the waiter before placing their order, ensuring a seamless dining experience.
