If you have a butcher anywhere nearby, that'll be your best option. If you don't, then talk to someone in Kroger's meat dept and see if they can't get you some short ribs. My butcher almost always has them.
Just keep in mind that they are a very fatty cut, coming from near the belly or plate area, so they have to be cooked long enough to render the fat.
But man are they a delicious, and very beefy tasting cut!
I'll be posting a braised short rib cook I did recently.
