Cool.......
It is just a matter of time.. One of my daughters (who really loves Pho & varies Viet foods) was in Japan for 4 years & when she finally moved back she ate @ her fav Pho place 4 times first week back.

There is almost no ethnic foods in Northern Japan... A few Indian but nothing else...
Is there Thai there yet??
We are now getting tons of "Fusion" restaurants, some are good, other things are just wrong..
We went to a dinner @ some place my son picked & his wife (she is Viet) & I both ordered a "Korean-taco"........ What a mistake that was..
