IS restaurant Ivan Mudronček Bernard Badó Petr Vévoda

Basic goals 1/3  We would like to keep a record of dishes ordered by customers and compare ingredients consumption with their estimated amount for each dish, also punish employees according to company rules when there is undeniable difference during their shift.

Basic goals 2/3  So the restaurant decided to start customer loyalty program. This program should work on giving a restaurant card to a customer who, had already eaten in the restaurant. With that card, customer can eat food in the restaurant with 10% sale. He can also collect points when he eat at the restaurant.

Basic goals 3/3  We also care about our customers so when there is something that concerns you, you can leave note at our web page or in designated mailbox in our restaurant and our skilled staff will soon consider your complaint or idea of improvement.
