Yakitori Kokko is a breath of fresh air for lovers of authentic Japanese grilled chicken on the Peninsula, says K K. The owner, Keisuke Suga, also runs Kappo Nami Nami in Mountain View, and, like Nami Nami, Kokko has a classical minimalist design, with wood floors and ceilings, and sections divided by traditional-style curtains.
You order by the skewer, choosing the seasoning for each, like shio (salt) or tare (a soy-based sauce). Shio momo, or chicken thigh, "was dead-on perfect in all aspects. The standard must order," says K K. Chicken gizzard, or sunazuri, has good crunch. And chicken heart (kawa) is nice and juicy. Unfortunately, chicken meatballs with tare are way too salty; the version at Sumika is much better.
There are also some meat, seafood, and vegetable options, plus izakaya-type sides and fusion dishes. Bacon-wrapped asparagus is a nice one.
