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, 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. Depending on the season, they might be filled with peaches instead. Don’t worry, they’re just as good.
