Happy Bday to your son (didn't know that) -- it was Marie's bday, as well... and it was nice seeing you, and meeting your parents.I knew we would run into each other there eventually. 
That soy paper wrap roll is the Koko... and, notwithstanding your Japanese friend's advice to not mix wasabe and soy, the Koko roll is the absolute perfect mechanism to take advantage of the wonderful flavors that the soy-wasabe concoction brings.
That's why we call it the "burn" roll. Not your prototypical "sushi," but it is absolutely delicious. Even Murphy would like it, I think. Avocado, cucumber, imitation crab, tomago (sweet egg), wrapped in soy paper (tasteless).
Dip in the wasabe-soy... yum!
