This was being heavily advertised when I was in Japan a few years ago.
But yeah, I dunno. No way I'm touching the Grand Mac but the Mac Jr. doesn't sound bad. Having said that, I have maybe one McD's burger a year and it's usually a Quarter Pounder. I don't expect that to change.
McDonalds should scrap testing shit, and just roll out their Create Your Taste kiosks nation wide so customers can get the burger they want every time.
Forever ago I was in some podunk town in Northern California and they were testing a Big Mac just like that. Two quarter pounder patties called the X-Mac, I think it was. It was glorious. I've longed for a day they would start testing it out again or roll it out to more places besides a podunk town.
