Only do interior upgrades when they are coins-only.

However, once you’ve upgraded to level 3 you’ll easily be able to replay a level and get the XP for that task.

For example “serve 3 glasses of ginger ale in 6 seconds” is pretty impossible if your ginger ale machine is just at 1 or 2 servings at a time. Getting 3 stars and/or serving customers quicker thanks to the upgrade will often trigger those tasks. You’ll probably be able to get 3 stars in the at least the first 1 levels of each restaurant once you’ve done some upgrades. If you are playing additional levels for the sake of winning XP and leveling up, go back and play the early levels after you’ve upgraded some ingredients or equipment. You can earn experience points through the “tasks” for each restaurant, in addition to playing levels. You level up in the game each 10,000 experience points. You’ll win 7 gems each time you level up in the game.This is an easy way to keep track of whether or not you can play the casino again as well, if you do them together. This way, if you view a restaurant before the 24 hours is up, the timer will still be ticking away telling you how long is left until you can claim your earnings for that day. Wait to click the ‘claim’ button on a restaurant until right after you win at the casino.

Each restaurant that you own will earn you coins every 24 hours as well.This resets every 24 hours and is the best way to get gems. Once you’ve unlocked the Casino, play it every day at the 500-coin level until you win 15 gems.
