A hidden fourth-floor Japanese soba and tempura specialist with excellent craftsmanship and warm chef-led hospitality, though portions can feel small and a few older or isolated visits reported inconsistency.
Mitsumori earns its standing through excellent food quality, with handmade soba and thin-battered tempura drawing consistent praise, alongside attentive service that includes chef check-ins. Slightly less reliable consistency, a few older reports of slow service, and a less polished surrounding food hall keep it from a higher standing. Unusual review patterns, including recurring staff-name praise, add some uncertainty to the assessment.
Mitsumori is the sort of place you can miss twice before realizing the reward is upstairs: a Japanese specialist tucked into Isetan's fourth-floor dining area in the middle of Bukit Bintang. Once found, the mood is generally calm, clean, and comfortable, with the chef and staff often adding warmth; one diner described the experience as discovering a quiet corner above the mall bustle. The main caveat is practical rather than glamorous: Japanese-only signage and the surrounding dining space can make the arrival less intuitive. The kitchen's strengths are focused rather than theatrical. Handmade soba arrives firm and springy, while the tempura is repeatedly praised for a delicate, crisp coating that avoids greasiness. Fresh seafood, grilled mackerel, sashimi, seasonal vegetables, and thoughtful guidance from the Japanese chef make this a strong destination for soba and tempura devotees. It is elevated traditional Japanese cooking, not an experimental fusion menu; diners pay for technique and ingredients more than oversized portions. A few older reviews describe slow service, ordinary side dishes, or disappointing prawns, and one recent detailed review raised a cleanliness concern, but those reports are not the dominant pattern. Families can make it work, especially with fried chicken, chicken wings, potato salad, rice-based sets, vegetable tempura, and approachable soba on the menu. It is not a dedicated children's restaurant, and the refined, quieter setting plus seafood-focused courses may be less comfortable for very picky eaters. For children willing to try noodles or lightly fried food, however, there are several realistic choices.
The handmade cold soba and delicate tempura are the safest bets, with options ranging from a RM13 vegetable bite to a RM350 tasting menu.
The main surprises are finding the restaurant inside Isetan, paying premium prices for sometimes modest portions, and checking the soba sauce if you avoid alcohol.
Expect a quiet, chef-led Japanese setting above the mall, with a generally comfortable mood but one cleanliness caveat worth knowing.
