As foodservice concepts go, delis may not seem particularly trendy, but they’re actually very much on trend. First introduced to the U.S. in the late 1800s by German immigrants in New York, delis’ enduring popularity has everything to do with what and how modern consumers like to eat. Freshness, transparency, customization, quality, variety, convenience, mobility — all of that and more becomes standard fare at delis and deli-inspired sandwich concepts. And while classic Jewish delis have changed little over the years (they’re classic for a reason), modern delis are well suited to maintaining core brand promises while incorporating current culinary trends.
