Menu of Mogu Mogu Onigiri Shop in Rosemead, California, USA

Menu Overview

Mogu Mogu Onigiri Shop, nestled at 3365 Walnut Grove Ave in Rosemead, CA, is a culinary gem for lovers of authentic Japanese onigiri and donburi. This restaurant offers a focused yet thoughtfully curated menu that celebrates the simplicity and depth of traditional flavors wrapped in modern execution. From the moment you step in, the cozy atmosphere and attentive staff set the stage for a memorable dining experience.

The true stars here are the onigiris—handcrafted rice balls filled with fresh, high-quality ingredients and wrapped in expertly cooked seaweed. The Eggplant Onigiri delivers a delicate balance of texture and umami, with a slight crunch that complements the soft rice. The Salmon Onigiri is savory and aromatic, enhanced by the subtle freshness of shiso leaf, which adds a refreshing herbal note to each bite. Both variants showcase Mogu Mogu’s mastery of rice preparation—slightly al dente, sticky enough to hold, yet light and fluffy on the palate.

Beyond onigiri, the Donburi bowls truly shine. The Karaage Japanese Fried Chicken and Egg Bowl features juicy, perfectly marinated chicken, crisp on the outside and tender within, paired with a comforting, fluffy egg. The Buta Kakuni (Braised Pork Belly) and Egg Bowl is a showstopper—the pork belly melts with every forkful, enriched by a marinade that balances sweetness and soy-based depth. The Spam and Egg Bowl elevates a humble ingredient by grilling spam with a sesame-soy tare sauce, imparting a slight sweetness and umami kick that pairs beautifully with rice and egg.

Complementing the solid food offerings are the specialty drinks like the Iced Strawberry Matcha Latte and classic Iced Matcha Latte, both crafted from real matcha and whole milk. These drinks offer smooth, refreshing layers of earthy and fruity flavor, with the option to add whipped cream for a decadent finish. They serve as perfect palate cleansers or indulgent treats alongside your meal.

Even small touches like the crunchy shrimp chips add texture contrast, rounding out the meal with light, salty crunchiness. Customer reviews frequently highlight the consistent freshness of ingredients, skillful cooking, and warm, welcoming service by the staff—which transforms a simple lunch or snack into an inviting experience.

While Mogu Mogu Onigiri Shop focuses on lunchtime service and has limited hours, the quality it delivers during those hours is well worth planning around. The intimate location in a plaza with limited parking and a single access point is a minor inconvenience compared to the culinary rewards inside. For enthusiasts who crave authentic Japanese tastes and crave thoughtfully prepared rice dishes, Mogu Mogu Onigiri Shop is a must-visit.
