They dont generally last too long. Fuckin 5 guys i think it is keep on doing 'pop up' restaurants that end up with dickheads queuing for hours only for the place to sell out of their shit quick. Its just hyped shit. Carls Jnr is actually popping up all over the place in Melbourne, have had it, its kind of like hungry jacks (god tier burger king) with a triple wait time, and over this side of town ive actually seen a couple of Taco Bells, as opposed to our Taco Bills which every location looks dank as fuck and has been around for decades. Theres only one place i know of that i can find a proper philly cheesesteak tho and its a pain in the ass to go to unless you live in the middle of the city. Jumping on something like menulog, youll find that a shitload of places do burgers like them fucking full on bacon brisket bacon cheese bacon pulled pork bacon bourbon bbq sauce, most of them are owned by the same people but theyre 'random american style cafes' Then there is shit like 'Bettys Burgers and Concrete Company' which is .... just fucking burgers but you pay a retarded amount because 'americana' or something.
