Diner Fever: 쿠킹 게임

This is the game I've been playing the longest, and it's surprisingly addictive haha. Before, when I couldn't upgrade because I lacked gold and missed clearing a stage, I really felt the urge to spend money. But now, I've cleared the final stage and am waiting for an update. I'm so bored that I'm replaying old stages and pre-collecting resources. Because of that, I feel like I clear new maps quickly when they get updated..

I play it sometimes. It's nothing special, just a common tycoon serving game. It's fun. The difficulty increases as you progress, but if you play casually, you can enjoy it with items you get for free.
