Summer is nearing its end and we're only weeks away from full-on fall. As we begin to feel the chill in the air and start revamping our autumn wardrobe, we also realize it's time to go back to school. We know, we know, you've graduated years (or months) ago, but hear us out. Since we firmly believe in lifelong learning, we have rounded up some of the most trendy and unique classes NYC has to offer. Invest a small portion of your time and get the best out of learning something new - whether it's foodie knowledge, a refreshed mind, or a new friendship.
