Duke's Old Fashioned Onion Burgers will bring Oklahoma-style smashed onion burgers to San Diego when it opens later this year.
From Frank Schulz, a San Diego native who left for 34 years and since returned 6 years ago, Duke's Old Fashioned Onion Burgers is currently in the process of installing within the space that last housed a Starbucks Coffee in La Mesa. The new eatery will offer a menu centered around Oklahoma onion burgers, where thinly-sliced onions are smashed into the patty while cooking on a flat top grill.
Duke's Old Fashioned Onion Burgers will be a fast-casual concept with indoor and outdoor seating. The menu will feature fresh Angus beef patties cooked to order. Patrons will be able to top their burger with a variety of free toppings, including cheese, lettuce , tomatoes, jalapeños and house made pickles. Duke's will also offer a selection of fresh-cut, double-fried French fries, including Spanish fries with onions and jalapeños, bacon cheese fries, steak and blue cheese fries, taco fries, and pesto fries, as well as handmade milkshakes and other soft drinks.
