Li-Lac Chocolates, New York’s oldest chocolate maker, turns 100 on Friday, Oct. 13. To mark the occasion, the company is throwing a birthday party at its factory in Industry City, Brooklyn — and you’re invited.

The event is scheduled to run between the hours of 10 a.m. and 5:30 p.m., during which the public will have an opportunity to sample the company’s small-batch, hand-made chocolates and receive 20% off any purchases.

There will also be door prizes with the first 100 people in line receiving a free gift box and the first 300 people receiving a 2-pound Vintage Gift Box valued at $100 for $19.23.

To get to Li-Lac, take the N or D express train to the 36th Street station.
