In We Are Cooking, you can move to a new restaurant after fully upgrading the current one and having enough currency.
How does it work?
By completing levels, you earn in-game currency, which can be spent on various upgrades in the "My Kitchen" section — increasing portion sizes, their value, or speeding up preparation. Each upgrade has a level, shown as yellow stars.
When you purchase an upgrade, these stars fill a special progress bar at the top of the "My Kitchen" tab. Once all available upgrades are purchased and the maximum number of stars collected, the progress bar will be completely filled.
After that, a new restaurant becomes available. You can purchase it with currency, and the game will automatically start loading new levels after purchase. You'll continue your culinary adventure in the new restaurant, unlocking new recipes, cuisines, and upgrade possibilities.
Also, remember that you don’t have to move to the new restaurant right away — you can continue earning currency and refining your skills in the current one!
