Below your Gourmet Points bar is your restaurant's rating, if you have joined the Restaurant Cg Guide. If you click your Gourmet Points bar, it will tell you how many points are required for the next level and what you will be awarded. Upgrades include larger restaurant interiors, more employees available for employment, more garden plots, and also more dishes available to be served. Customers start using toilets at level 8. Drinks open at level 9. From level 5, you get 1 bonus ingredient on level up. From level 65, this increases to 2 ingredients per level.
