I’ll provide a counter point here. My nearby F&C is run by an Asian family, mostly the Dad and is brilliant. A kids pack is more than enough for me for lunch - flake, dim sim, potato cake and a pile of chips for $7.50. brilliant.
The F&C nearest my previous place was at the end of my court, maybe 100 meters walk. Also Asian run, also ace. Always the extra potato cake with any vaguely decent sized order. How I never got fat is some sort of miracle.
I’ve tried a few of them, and they are all exactly the same. And there’s nothing particularly American about them; they’re just burgers. Melting the cheese into a gloppy mess and putting some kind of ambiguously interesting variant of mayonnaise on them doesn’t make them any more unique.
And then half of them put chicken salt on the chips, lol.
