In 2018, 2,500 people stopped by the event and the festival was able to raise $14,000 for local groups.
No advance tickets or registration is required. Admission is $2 for adults. Admission for children three or under is free. Credit cards are usually accepted at the event, but cash is recommended.
In addition to chocolate, the event will have a room set aside for live family-friendly entertainment throughout the day. A lecture will also be held on how chocolate was made in colonial America.
