I really like the concept as a person who was brought up in Tokyo ie part conbini, osouzaiya, deli. I have several minor issues with their food quality though. Ordered deluxe okonomiyaki which was closer to Hiroshima style with noodles, but the noodles were hard. Crunchy hard. And way, way too much mayo . All I could taste was mayo. Sickening amount of mayo spread on it. Next item I purchased was 5 pieces of oinarisan ie stuffed deep fried tofu skin with different topping. Topping was generally ok, except few pieces slathered with too much mayo again. Go easy on mayo and they would be better. Another problem I had with is hardness of rice. I find this problem with all US based supermarket, Japanese grocery store prepared sushi and rice offering. Rice found in the US markets are too hard. Go to Japan and you will see their rice for sushi, bento is softer. I can make soft rice in the US, so it is how these places make rice. Since these items are normally refrigerated, the cooked rice becomes even harder in chilled dry environment like coolers. Cook the rice softer like in Japan. I do wish they continue to improve on their quality and I am cheering for them to get better. Shala la had the great ramen when they were in Mountain View.
