Starting Oct. 2nd MOS Burger will begin selling "top quality" burgers featuring Japanese meat. There is a regular burger and cheeseburger, but the thick slice bacon burger is the main burger being advertised. From the patty photo, you can see both a cow's and a pig's head, meaning both pork and beef. You can also see in the other photograph how thick that bacon slice is. The thick bacon slide burger will sell for 420 yen. One more thing, the way it is written in Japanese makes it sound more like a chopped beef sandwich than a hamburger. とびきりハンバーグサンド、厚切りベーコン
