Hipsters in HK are not the bearded ones, and they don't eat expensive gourmet burgers (though we all know HK has plenty of those overpriced and sometimes tasty buns). They're not made in the same way, but the end results are like 80% fascimiles from my experience. What we want though (OK, I want) is In N Out! They are not hipster and not expensive but very tasty. Sigh. Their conservative growth family based decision making is quite annoying to fans who don't live in California/some neighboring states.
I've had shake shack before, and their stuff was good. Triple-O's I'd rather not do. I guess if I had to choose between McD and them I'd go Triple O, but wouldn't choose them otherwise.
