Devil's Dozen Donut Shop in downtown San Diego's Little Italy debuted in 2015 from the same SDCM Restaurant Group behind Kettner Exchange, operating a walk-up window at 2001 Kettner Boulevard that shares a building lot and rooftop patio with its upscale sister restaurant. The curated daily menu runs roughly a dozen varieties — Devil's Chocolate (chocolate old-fashioned with dark chocolate glaze), Devil's Vanilla (chocolate dough with vanilla bean glaze), Nutella cream-filled, guava cream, and seasonal rotations like Girl Scout cookie-inspired specials — baked fresh hourly until sold out, a limited-batch craft approach that contrasts with the higher-volume novelty donut format at Donut Bar & Bakery elsewhere downtown. Premium chocolate, seasonal fruits, and quality essences top a dough program that splits between raised and old-fashioned cake bases. The rooftop patio above the walk-up window offers one of the best donut-eating views in the neighborhood, looking out over Kettner Boulevard toward the harbor. Locally roasted coffee complements the donut case from the same compact counter, a morning pairing that lands in the same Kettner corridor as the craft-beer tasting room at Stone Brewing Tap Room - Kettner down the block. The highest-demand weekend specials — seasonal fruit glazes and filled varieties — regularly sell out before noon, making early arrival the only guaranteed path to a full selection.
