Translation for those interested:

One of the mistakes made at the beginning of the game is to put the kitchen in the corner (I did it too), and as the area expands in later levels, the counter space may not be enough to carry food from the kitchen to the tables. Another suggestion is for those who want achievements, let me tell you a few achievements that may be overlooked: 1. To give a name to a staff member 2. To click on the sign 3. To click on the sign more times 4. To click on the sign at the entrance of the inn more times. Have fun. ;)
