Before Sushi Sonagi, there was Katsu Sando. This tiny sandwich shop in Chinatown (with a second location in Monterey Park) is run by the same chef and pays homage to Japanese convenience store foods, like grab-and-go onigiri, fried chicken, and, most importantly, excellent sandos. The sandwiches are noticeably jumbo-sized, filled with creamy slaws and panko-crusted proteins, and make for the kind of quick but comforting lunch that’ll keep you full until dinner. Katsu takes sandwich making seriously. They bake their honey milk bread in-house, which you can enjoy soft and plush in a cold-case egg salad sando, or crunchy and toasted in one of the menu’s made-to-order options. Fillings range from fried bricks of honey walnut shrimp to kimchi brown butter chicken to pork katsu so juicy it requires dabbing your chin with napkins between bites. The rest of Katsu Sando’s menu includes more upgraded convenience store staples, like hambagu steaks, a burger, breakfast burritos stuffed with tiny arabiki sausages, and bulgogi onigiri that are great eaten later that night on a couch.
