The Meltdown in Chula Vista is a delivery-only grilled sandwich concept from Denny's, Inc., operating through the E Street kitchen at 692 East Street in the 91910 zone. Signature melts layer sharp white cheddar, caramelized onions, and braised brisket between griddled bread, a handheld format that shares the same Chula Vista delivery radius as the pies at Giant Pizza King. The all-day breakfast lineup includes egg-and-cheese melts on sourdough alongside the lunch roster of Hot Mess and Giddy Up combinations. Dessert melts — including a pound-cake-and-cheesecake Treatin' Myself option — extend the concept beyond savory into the same sweets-delivery lane tapped by concertgoers near North Island Credit Union Amphitheatre. Each melt is assembled on thick-cut artisan bread, pressed on a flat-top griddle until the cheese pulls, and boxed with a choice of seasoned fries or coleslaw for DoorDash-exclusive fulfillment.
