Seventeen percent of consumers and 31% of millennials often take pictures of their food and post them on social media when they visit restaurants, according to the 2018 Generational Consumer Trend Report from Technomic. Sandwich chain Quiznos, Denver, launched the Magic Mushroom Melt earlier this year, which has garnered attention among younger audiences. The photogenic sandwich features a triple serving of mushrooms, tie-dyed Swiss cheese, bacon, neon purple-and-green ranch dressing and tomatoes on tie-dyed white bread.
