Fox's Giant Pizza occupies a storefront on Santee's Mission Gorge Road corridor near the Father Junipero Serra Trail entrance, serving hand-tossed pies in sizes up to 28 inches alongside calzones, stromboli, and hot subs. The dough is pressed and proofed on-site daily, then loaded with whole-milk mozzarella before firing, a scratch-production approach that pairs well with the single-origin pour-overs at The Lean Bean one block east on Mission Gorge. San Diego County Health Department inspections have returned a 98-out-of-100 score for the kitchen. A gluten-free cauliflower-crust option runs across the full specialty pizza lineup, including the BBQ chicken, Philly cheesesteak, and white-garlic builds. The outdoor patio seats a dozen and accepts dogs, creating a post-hike staging area for walkers returning from Mission Trails Regional Park before evening drink options open up at Alibi down the road.
