A solid 3.5 stars (I'm Korean and was raised in L.A.,  so my standards are pretty high).  Like Mexican and Chinese food, good Korean food is another thing that is hard to come by in the Valley (near Tempe).  The only places that I think are even worth mentioning are: Chodang, Hodori, and Takamatsu.  All three have their pros and cons.  I have posted separate reviews of Chodang and Takamatsu.  Besides going to Chodang and Takamatsu for specific reasons, Hadori is where my husband and I go if we have unspecified hankerings for Korean food.  They have a wide range of offerings and they are all pretty good, and my husband likes their BBQ the best.
