This is a pretty good game. But, it is not very relaxing. I do not think they give you enough time to make food- and the customers? Jeez, they they get mad so easily! So, if you think that this is just a relaxing game where you make food, you are horribly wrong!
I love this so much! It is very fast-paced but easy at the same time. In-app purchases are available but you can get them without real money by earning enough in-game cash. It is clear that you use real money to buy cash.
