7:30 am - 8:30 am Meet & Greet at coffee shop in the corner of the plaza (not the drive-thru one out on 34th). No purchase necessary.
Every day is International Coffee Day!
A quick googling of the history of coffee shows a consensus that coffee originated in Ethiopia and trading of the beans spread first to the Middle East, and then the rest of the world--thank goodness!
I've never been to this particular coffee shop, but it looks interesting and they have indoor seating, so there's that. Bring your trackables for trading or showing off, bring some conversation, bring a friend or two!
