Up here where I live north of the border in Canada, our nicest Italian restaurant in town is named Abruzzi, and nothing on the menu is Abruzzese. The owner’s parents are from Abruzzi, and while the food is tasty, it’s pan-Italian and North Americanized.
When I have taken part on the annual ski trip to Tremblant (7 or 8 times), with the Friulian club, the bus has around 20 people with Friulian roots, a few with roots in Trento, one or 2 people from Naples, one man from Bari, a few people who are half Calabrian, and 4 guys from Abruzzi. When we have our big potluck, the guys from Abruzzi always make their agli e olio. That’s the only Abruzzese dish I’ve become familiar with!
