Tips from locals
Very new museum, very central, and free! Also convenient if you plan on visiting a palace or two. It's down the street from Deoksugung palace, about five minute walk. May have an exhibition or similar that make a good bonus.
The best overview of Korean history that I know. Plus, there's a huge mini-city laid out on the floor for you too look at.
