Located on Route 66 in the western suburb of Glendora, The Donut Man has been around since the ‘70s and is a flat-out classic. While they have a full menu of all sorts of very good donuts (shout out to the tiger tail and apple fritter), but you’re here for the famous strawberry-stuffed ones. They’re basically donut pita sandwiches filled with fresh, sugar-glazed strawberries and they ruin every other donut in existence. For a few weeks out of the year, they sometimes have ones filled with fresh peaches, too. If so, lucky you—they're an even rarer treat.
