Running a successful restaurant in Roblox Restaurant Tycoon 3 is about more than just placing tables and serving food — balancing profits, upgrades, and customer satisfaction takes time, and codes can help smooth out that process.
Most of your success comes from serving customers, earning cash, and reinvesting it into better layouts, décor, and staff. Codes usually provide Diamonds or Cash, which are especially useful when you’re saving up for upgrades or testing new restaurant setups. With that in mind, here are the currently working codes in the game and how to redeem them.

What are Restaurant Tycoon 3 codes used for?
Restaurant Tycoon 3 codes are mainly used to give cash and diamonds, both of which play different roles in running and upgrading your restaurant. Cash supports day-to-day growth like expanding your layout and improving operations, while diamonds (gems) are a premium currency used for higher-end features.
Diamonds let you level chefs beyond Level 3, buy furniture from the EKEA shop, unlock worker hats and accessories, and purchase music discs that improve your restaurant’s rating and atmosphere.
Where to find more codes
Restaurant Tycoon 3 doesn’t release codes on a fixed schedule. When new ones do appear, they’re usually shared through official Roblox announcements, update notes, or the game’s Discord community. Since they can be easy to miss, bookmarking this page is a simple way to stay up to date.
