Knockout Deli & Kitchen builds overstuffed gourmet sandwiches at 6635 Alvarado Rd in San Diego's Grantville neighborhood, 92120, operating out of a counter-service space inside a commercial strip near Alvarado Hospital. The sandwich roster runs 8-inch and 12-inch sub formats with signature builds: the Fat Tony layers hot pastrami, mortadella, salami, and melted pepper jack with Dijon mustard and banana peppers, while the John Gotti stacks hot pastrami with avocado and pepper jack on a toasted roll. Knockout also operates a second location on Convoy and Raytheon Rd in Kearny Mesa, giving the brand a two-storefront footprint across San Diego, and both kitchens run a catering program serving corporate events and social gatherings throughout Southern California. Every sandwich ships with mayo, mustard, lettuce, tomato, red onion, pickle, and pepperoncini on the side, plus a choice of potato salad, mac salad, green salad, or fruit—a full-plate format that separates Knockout from grab-and-go chains on the same Grantville corridor where Gaglione Bros Famous Steaks & Subs runs its own cheesesteak-heavy menu. Hot sandwiches include a Philly cheesesteak in 8-inch and 12-inch builds, a teriyaki chicken Swiss melt, and a 9-inch torta that loads roast beef, pastrami, turkey, ham, salami, and melted provolone onto a single roll. The "Knockout Way" upgrade adds extra meat, avocado, and the house knockout sauce to any sub, pushing the 12-inch format into a two-meal portion for most appetites. Healthy wraps, salads, and a breakfast menu that fires up at 7 in the morning give the deli a daypart range that most sandwich counters on Alvarado Rd do not attempt. The kitchen identifies as a small business and LGBTQ+-welcoming, and the Grantville storefront draws a lunch rush from the surrounding office parks, hospital staff, and auto-shop crews that populate the Alvarado corridor. Morning pickup pairs naturally with the Grantville coffee circuit, where CUPPA CUPPA COFFEE COMPANY pulls espresso a short drive up Mission Gorge Road for the same commuter traffic that feeds Knockout's breakfast window. White albacore tuna salad, homemade egg salad with crispy bacon, and a hummus-avocado wrap round out the lighter side of a menu otherwise built around stacked deli meats and melted cheese.
