Thank you for that. Also as an American, I too have never heard of this. When I saw the words Alice and restaurant, I thought back to the TV sitcom called Alice from the 1970's-1980's who worked at Mel's Diner.

As far as American Thanksgiving staples I'm aware of, it's:

* Macy's Thanksgiving Parade

* (American) Football

* Turkey dinner

* Charlie Brown Thanksgiving (+ maybe Garfield)
