At level 30 the Catering Plot gets unlocked where you can deliver orders for exclusive events in your town.
To deliver orders at Catering, you need to have dishes ready and deliver them to earn Coins and XP. You can also get help from friends to complete Catering Orders!
Events that are opened in catering are timed; hence make sure you cater to all orders before the event wraps up to be rewarded with a full order bonus as well as an additional bonus for completing catering orders well ahead of time! You can also buy your way out for additional time if you are cutting it too close by spending some Cash.
At any point you want to cancel a catering order, you can simply go ahead and do so. The catering truck will return with a new order after some time.
