Since I don't think I've seen it discussed here, I thought I'd mention Dong Baek. There's a notable lack of good Korean in the city East of, say, Japantown. I went alone, so I only tried the Kal Bi, but Dong Baek had pretty good meat and panchan.
It was good and I'll definitely come back though it's nothing truly amazing for the price (which is a bit on the high side for something in the tenderloin).
[It is not a tabletop grill: they cook it in the kitchen.]
It's on O'Farrell not too far from Golden Era Vegetarian.
