Another shameless local plug that justifies the "I love Franklin Ave" tag, coming right up. I've been making at least a weekly pilgrimage to 3D's Bakery and Restaurant on Sterling and Franklin and I'm always glad when I go. Their patties are positively scrumptious, with flaky crusts and fresh, tasty fillings (for the vegan/vegetarian crowd out there, their veggie patty is head and shoulders above any others I've had). Patties often get maligned as cruddy fast food (amongst the new-to-the-neighborhood-earthy-crunchy crowd that I run with, anyway), but these are anything but. Plus, for a buck fifty, they're a perfect pre- or post-drinking snack (conveniently located on the way to Franklin Park for me).
It's not just the patties that draw me to 3D's, though--I've become a devotee of hard dough bread. The 3D's loaves (pictured above), are perfect for sandwiches, and as I found out on Thanksgiving, they make for the best damn stuffing I've ever had. The bread is "hard" because the dough is chewy and moist, almost like a very dense sourdough, but slightly sweet, in a yeasty, bready, absolutely-awesome-when-warm-with-jam kind of way. It also hangs together and doesn't get soggy, even laden with sandwich goods and condiments and rattling around in a backpack. The link above has a basic description and a recipe, if you're into bread making.
As a final note, the service is some of the friendliest on Franklin, and they're an institution--I found out today when I picked up my weekly loaf that they've been in business for 29 years and counting.
