I have been here quite a few times now. I always go with my boyfriend who is half Korean. We have tried several of their menu items and both us being well versed in Korean cuisine agree that the food is always delicious. I have only been disappointed once by their food, and that was when I order the Hae Do Bap(pardon the spelling) which is sashimi over salad and rice with a spicy korean sauce. The sashimi was served to me still partially frozen which I thought was quite horific, not to mention I was seriously craving Hae Do Bap that evening so that was a huge let down. The service is alright nothing fantastic and nothing terrible. The waitress we usually get seems quite bored which can throw off the mood sometimes, but I overlook it because the food still comes in a timely fashion and is always tasty (except that one time of course).
Now recently I've been taking my mom and step father there for dinner and they enjoy it as well. My mom always gets the seafood tofu soup (Hael Mul Soon Doo Boo?) and my step father gets korean barbecue. He has fun being able to grill up his food and rolling the meat up in lettuce wraps. The portions are never an issue, every item so far is perfect for one person and sometimes two depending on how hungry the individual is.
In short, food is great, just don't get that sashimi salad I was talking about! Service is alright which is why I am giving the place four stars. I will definitely continue to eat here. I suggest they work on their service though since it seems like that's the main complaint from everyone else!
