I lived in Asia, and pretty familiar with Korean quisine. This is very mediocre, non-authentic Asian food restaurant with pricey dishes!
I ordered shrimp japchae, and a small portion costed me $14! They don't give you any additional sides with it like all other authentic Korean places do.
To be fair, the dish was pretty tasty, so giving them 2 stars.
Place is small, not cozy and nice, I wouldn't want to sit there and eat, take-out is the best way to go if you really want to try this place out
