Owner Jason Wojnarowski opened the Donut Crazy on October 26, 2016 to provide a relaxed atmosphere for customers to eat, socialize, and study. It's slowly becoming a location that's beginning to garner the similar levels of popularity as nearby student hangouts Toad's Place and Ashley's Ice Cream Cafe.
