Highly recommended. Had 3 of my qualifiers for authenticity: kids (of said ethnicity) running around in kitchen, restaurant located in back of (said ethnicity) grocery store, and bars on the windows (although minimal). The waiters were young Korean kids who spoke perfect English and very friendly- there is a bell at each table that you ring when ready to order. The menu is pretty big and has pictures of everything. Go check it out.
PS Bulgogi Pork with vegetables is what I had - delicious (and super hot).
