This becomes even more useful in the later levels when you have to work with multiple ingredients. 2. Master previous levels before new restaurant Every now and then you will unlock a new restaurant. Although it’s basically the same thing in terms of gameplay, you will get new ingredients and new items to prepare for your customers. My recommendation is to make sure that you master all the previous levels before starting work on the new restaurant, because otherwise it will be more and more difficult for you to come back and master the previous levels. The thing is that you get used with how things work in a restaurant and therefore it’s easier for you to complete the more difficult challenges that come from the later missions. If you move to the new one and come back, the placement of the ingredients and the way things work won’t be as familiar as they were and you might struggle to complete the difficult levels. So complete everything before moving on!
