The fourth Let’s Talk About Food Festival returns to Copley Square on Saturday, October 3—this year as part of the city’s first HUB Week celebration. This festival lets participants dive into the most important food conversations and debates happening in society today. Through hands-on cooking demonstrations, edible gardens, and more, participants can also explore how to take advantage of the food around them by cooking better and eating healthier.
