Sometimes you just want some tang. One of my favorites is Galbitang made from good beef bones in a clear broth. Good places will have their bones simmered for a long time and the meat and connective tissue should be very soft. One of my favorite places for this is Myeongin Deungshim in Bangbaedong. I think this place is a chain but this place really does it well here and it is famous at lunchtime. The broth is rich yet light and they don't skimp on meat. The meat is good quality as well (and so is the rice).
So if you are looking for a good Galbitang place. Come here!
