You have a restaurant on the seaside and you make a living serving dishes and drinks to tourists who come to the beach. In each level you have to reach a certain amount of money to pass to the next level.
To move from one place to other, click on the blue stones indicating where you want to go. When the tourist comes, click in his table to know what he wants, then click on the chef to deliver the order; when it's ready you have to click the dish and take it to the client to receive his payment. If the delivered order is wrong it will be rejected and you'll have to throw it to the trash can (by clicking at it), and of course you'll lose money and time.
