How One Twenty Three Burger won local hearts
One Twenty Three Burger Co succeeded by refusing to compromise on ingredients despite operating from a food truck.
The decision to use 100% American Wagyu beef immediately separated them from every other mobile burger operation in the Inland Empire—this wasn’t typical food truck fare, this was premium meat prepared with skill and passion. 🥩
Owner Joe and his team’s professionalism became legendary among customers who appreciate the dedication to both food quality and customer service at every interaction.
The Chef’s Special burger quickly became the signature order featuring American cheese, bacon, grilled onion, fried egg, grilled jalapeño, pickle, and spicy mayo for $18—customers describe it as “fire” and the burger that will “put One Twenty-Three Burger Co. on the map.” 🔥
Bulgogi fries emerged as an unexpected star of the menu.
These loaded fries combine cheddar jack cheese, ground beef bulgogi, spicy mayo, green onion, and toasted sesame—reviewers consistently mention getting the bulgogi fries as “a good move” when visiting, with many saying they’re just as impressive as the burgers themselves.
The Wild Style Sauce developed a cult following among early customers who understand it’s the secret ingredient that elevates every bite—it’s become so beloved that the restaurant posts about how their first customers “know what’s up.”
Food reviewers on TikTok and Instagram declared it their “new favorite burger spot in the Inland Empire” and “the best burger I’ve had in awhile,” giving massive exposure to the small food truck operation. 📱
