Eataly stands for “Eating Italian” which encompasses the history and the food culture of Italy, the ease to prepare its dishes, and the many qualities that Italy has to offer. After five years of research and hard work, the first Eataly opened its doors in Torino on January 27, 2007, when an old vermouth factory was transformed into Eataly Torino Lingotto – the very first multifunctional marketplace dedicated to Italian excellence in the world. The rest is history! Since then, Eataly has expanded, with more than 40 locations throughout Italy and the world.

Founded in 1976 in celebration of the nation's Bicentennial, the African American Museum in Philadelphia (AAMP) is the first institution funded and built by a major municipality to preserve, interpret and exhibit the heritage of African Americans. Throughout its evolution, the museum has objectively interpreted and presented the achievements and aspirations of African Americans from pre-colonial times to the current day. The museum is committed to telling the story of African Americans in all its permutations: family life, the Civil Rights movement, arts and entertainment, sports, medicine, architecture, politics, religion, law and technology. The AAMP currently houses four galleries and an auditorium, each of which offer exhibitions anchored by one of our three dominant themes: the African Diaspora, the Philadelphia Story, and the Contemporary Narrative.

Farmers Restaurant Group
Farmers Restaurant Group
multi-city
When the members of North Dakota Farmers Union (NDFU) began talking about the future, they sought to provide a restaurant brand where consumers would benefit from a direct link to the source of foods cultivated on American family farms. And Farmers Restaurant Group was born. As we watch much of the restaurant industry cut labor costs and offer foods with additives to extend shelf life, we’re doing the opposite. We continually look for opportunities to add value to all our ingredients. We source pure ingredients in order to cook, mix, and bake our food and beverage items from scratch, in-house, every day, all while honoring American family farmers and their hard-earned bounty.
