He brought "Hato sabure", dove cookies. This is a fairly famous Tokyo omiyage. My name, Jonas, also means dove. I have been asked by Japanese friends to always bring hato sabure from Tokyo since I am also "hato".
Yesterday, three Japanese friends of mine also were in the magic bar at that time, and they thought it was hysterical that I was eating a hato sabure, since my name also means "hato", and since I was (and usually am when meeting them) wearing a t-shirt with animals being cannibals (yesterday it was a family of pigs eating fried pork).
Later, another group of 5 people who are my friends also showed up, so more than half the people that came yesterday showed up because of me...
