I'm really surprised that there's so many bad reviews for this place. My boyfriend and I come here at least once a month. Nak Won is a good standard place to go (other than the FMP location that place is really gross). They give you tons of side dishes with unlimited refills, and they have a large menu which I can appreciate, as it's probably a nightmare for them to deal with in the kitchen.
We're pretty boring and order the same food everytime, but we're usually happy with these ones: Soft tofu soup, jajangmyun, and the ttukbaegi bulgogi soup (so good...). The food isn't AMAZING - there's tons of places that specialize in certain dishes and it'll definitely taste better there, but Nak Won is a great place to go when you're hungry but you're not quite sure what you feel like eating.
