As the 2016 Winter Fancy Food Show returned to San Francisco, there was no shortage of snack foods, sauces, chocolates, ice creams, and more. In fact, in the show’s 41-year history, the 2016 Winter Fancy Food had the strongest attendance with close to 20,000 attendees. There were 1,500 exhibitors from across the United States and 28 countries were represented. Located in the Moscone Center in San Francisco, the show covers 215,000 square feet, which is the equivalent of four football fields. That’s a lot of food — and a lot of walking. Among the thousands of food products, three themes seemed to prevail.
