Thanks for playing! There are 3 lose conditions: If your hunger bar gets full, If you have more than 3 leaks, or If you didn't complete enough Daily Tasks when the day rollover. Did you see this screen? If so, the reason appears in the second line (if you didn't get it, might've been a bug). If you say you went through the restaurant, then it may be the leaks or Daily Task condition. Let me know :)
