I heart Nak Won! Particularly for lunch or dinner, dine-in (they also do take-out).
If ever you are super-duper, keel over and hold-your-stomach hungry for some spicy goodness... GO! As soon as you order, an array of little appetizers will arrive to stave your hunger and get your stomach ready to digest (kimchi is always among the apps).
The only reason I didn't give Nak Won a full 5 stars is because, after having sampled the entire menu, I just think they're sub par when it comes to beef ribs and soon dubu. Their prices reflect this, I suppose. But with so many options for Korean food in the area, you're bound to have a place or two that area especially good for these items (i have my favs, check for future reviews).
This place is good for guests who are doing Korean food 101. I've often brought friends and suggested they order some meat katsu, bulgogi, kan poong ki (sweet & spicy chicken) or bi bim bap (veggies, rice, beef, fried egg, & spicy sauce). Those "safe" items + the appetizers are a great introduction.
As far as I know, they don't serve dessert.
