Eddie Rocket's is an Irish chain of American diners. I've eaten there in Dublin. Although at least that location is downtown, and in a bigger building, not a classic diner style building. The inside is very much American Diner themed with vinyl seats, chrome, jukebox controls at the table, and of course the menu of burgers, fries, shakes, etc.
It's reassuring in a vague, indescribable way to know that while the Irish are exporting Irish pubs to the USA, we're exporting diners to Ireland.
Like, maybe they're passing each other somewhere over the Atlantic, and giving each other a friendly nod as they go along their respective journeys.
