This is korean style bbq super recommended! Its restaurant name is 김해뒷고기(gimhae dwit gogi) Copy the word and paste on googlemap
This is called 뒷고기 (dwitgogi), and it is a lot cheaper than 삼겹살 (samgyeopsal), this is because it is it is not the popular part of the pig (the belly or neck meat is very popular).
