Omatsu

It is at Av. Los Conquistadores 1005 in San Isidro, on the axis running up from El Olivar. Google classes it as an authentic Japanese restaurant and the house calls itself nikkei; what shows up flagged most is the house acevichado maki, and it is highlighted for cocktails and desserts. Our read: the split service — 12:30 to 3:30 and again 7 to 10:30 — is the mark of a kitchen that preps between services rather than a bar working straight through, which matters in nikkei; Sundays, by contrast, run straight to 5 with no dinner. With 4.7 across 128 reviews this is a neighbourhood room rather than a destination, but the S/ 60 to 160 ticket places it at the top of that category. It recommends booking, and has a bar and its own parking. The entry records a 2025 Summum nomination in Nikkei and Japanese Cooking. Curation note: the directory entry carried neither address nor district. Google marks only the toilets as accessible — not the entrance or the space — so the entry carries no accessibility attribute. The house publishes no website of its own, only the booking page; the menu remains pending.
