Chef Sang Yoon, the creator of Father’s Office gastropubs in Los Angeles, is opening a new fast-casual burger concept at South Coast Plaza on June 15.
Called Tiny’s Burger, the space is designed as a mix of an American burger stand with a Japanese Konbini-style snack shop.
The menu, created alongside Chef Nanor Harboyan, includes a dry-aged beef burger with caramelized gochujang and ssamjang sauce, a Tokyo Dog covered in bonito flakes and furikake, beef chili with Chinese chili crisp seasoning and miso mac ‘n’ cheese. Salt & vinegar tots are the only items from the Father’s Office menu, but Yoon plans to slowly bring over other favorites down the line.
There are also specialty Japanese snacks and drinks available to purchase inside.
Chef Yoon said he waited 10 years to open a restaurant at the Costa Mesa shopping center, looking for the right location. Tiny’s, in the former Boudin space, is near Caló Kitchen + Tequila.
“Tiny’s is about craveable comfort food refined with ingredients I love,” Yoon said in a statement. “We wanted to create a space that feels nostalgic but entirely fresh mixed with a menu that seems familiar yet new.”
