PLEASE KNOW THIS IS AN UNHOSTED EVENT!*
This event is hosted by another group called "Bay Area Friends of Europe" that aims to bring together Europeans living in Northern California. They boast an impressive >7,500 members. Despite being a general EU group, they do have many Belgian and Dutch members and can provide another opportunity to practice your Dutch!
If you plan to attend, please RSVP on their page, as they print name badges with your associated flag. This is your "ticket" to attend the event.
