There is no food I've wanted that I couldn't find here.
Went to an Israeli restaurant a few weeks ago.
I've also found a lot of food I would never have thought off, like baby bees
I found there were more authentic international restuarants (Indian, Thai, Chinese, French) in Osaka, Kobe and Tokyo than in anyplace I had been in the US. For some reason there are a lot of French restuarants. They are expensive, but really delicious.
