Was there yesterday....Pok Pok was not open but Koi Fusion, another big name food cart was. They are outside of security in the food hall near the back, in modified food cart style appropriate to Portland. The biggest drawback is of course, they are outside of security which begs the question are they really addressing flyers or visitors to the airport. There are many available food slots at PDX behind security, one of which was taken earlier this year by Burgerville. Lots of room to put lots of new options in.
