I am so excited that Pittsburgh has a Japanese comfort food restaurant. My husband and I went for the second time last night, and on either side of us were full blown Japanese conversations. So many Asians! So, you know this is legit.
We've tried a number of the small plates and the okonomiyaki. Everything is good. Don't come here looking for sushi - they don't have it. But the pancakes... oh, cabbagey goodness. They are difficult to describe... not exactly pancakes (because they are savory) and not pizza either, because the ingredients are cooked into the pancake itself. Perhaps consider adding a new term to your vocab: okonomiyaki!
Definitely sit at the counter if you can.
