An out-of-town friend and I went to Kobawoo (in the minimall, 698 Vermont @ 7th St, Koreatown) based on Jonathan Gold's review.
Delicious! And not too expensive for Korean food.
We both just got the bibimbap [=BBQ beef+veg] and tried all the little appetizer things. I'm no kimchi connoisseur but this kimchi was pretty great. Also, I don't know if bibimbap is always served in a very hot, heavy cast-iron bowl, but they did it here and it worked quite well.
We were also quite pleased a) to be the only gringos in the place from entering to leaving and b) treated very well by the waitstaff.
