Potato does the US

[Uncle]

for well known burgers in the US I always think of Jack in the Box = west coast, Five Guys = east coast (even though both are kind of all over)

have you had both? which is better?

Never heard of Jack in the Box. Sorry.

Five Guys were good burgers. But I've had them in Aus.

ah that's fine, I am a Five Guys fan

I think in a contest most people would say Jack in the Box is better, they have a "secret sauce" which is a combo of ketchup/mustard/mayo/A1 steak sauce/Worcestershire and hot sauce

probably not worth a special trip unless you're stuck in LA for a day
