Last couple of times I bought ribs to use for korean BBQ from Lotte or Super H have been dissappointing. The quality or the amount of meat on the LA style (I think it is called flaken cut) was not that good. I've notices they also "hide" the really poor cuts on the bottom.

I want to do korean BBQ this weekend. Where can I source the best ribs for korean BBQ?

BTW, I've also been curious, which is the primal I would by for korean BBQ if I wanted to try to butcher myself?

Soup

Korean Korner is the place to go! I've bought them there several times and the quality has been good-- not too fatty, consistently sized, and I think they've generally been about $5/lb.

Latin Markets cut the ribs to the size you want, not sure if that helps broaden the search.

I think it's flanken or (as my Korean Mother-in-law calls it) California-style kalbi. I get mine from the Global foods in Woodbridge or Manassas. I've never had a problem with the quality and they stock it in quantity. If you have the freezer space it's much easier to marinate enough for a few meals then freeze the rest.

I always buy meats from Super H but didn't get poor quality ones so far. I pick the rib meat from the special meat corner (black shelf) between fish section and meat section. The rib meat I am buying has no bone in it and is rolled.
Of course, it is a bit expensive than ones in the meat section but it is worth.

I just pick some of that up on Monday. It was about $9/lb. Not cheap but I suppose you get what you pay for.
