It turns out that James co-owns a restaurant in Berlin Germany called Nalu Diner http://www.nalu-diner.de/

The "restaurant" section mentions that James grew in up in "Indiana and Hawaii". Seems he lived in Berlin for a while too.

The address is Dunckerstraße 80a, 10437 Berlin - just a few blocks away from Dr Pong, which is located at Eberswalder Str. 21, 10437 Berlin

If you map both of these locations, they are approximately 800 yards away from each other.

We know it is James Alefantis from this article https://www.mrporter.com/journal/mr-porter-eats/the-worlds-best-diners/795 from April of this year! He still owns it.

That's an insane "coincidence" considering people were investigating Dr Pong in Berlin for the last month.
