The owners are Korean...the cooks are Korean...if you want to eat the good food on the menu, order the Korean food. (btw--I'm Korean too).
We've been here 3 times and have order the Kalbi, bi bim bop and bulgogi...all were pretty darn good considering the price (cheap) and the fact there aren't any casual inexpensive Korean restaurants...
I didn't try any of the other food on the menu (ie: hamburgers?) so perhaps the less Korean/Hawaiian foods aren't very good.
Regarding customer service.......it's an inexpensive order and eat place in a college town...as long as food is good and service is quick, then it's a win in my book.
