I like the concept of small fold-out maps, as it is much less cumbersome than a large map that you have to unfold and which may be prone to rip due to its size. However, this map book is woefully incomplete. I am targeting interesting food alleys from the Seoul Food Tour with Haechi, which is on the Seoul official tourism site. Unfortunately some of these areas are not covered by the map at all! They are in Seoul, the city, not in the outskirts, and are not simply not in this map book. It's a terrible oversight, and so lazy considering you only get six maps, some of which overlap! It's also extremely difficult to find anything on the map, even if you know the subway station you're looking for. There needs to be a overlay of the map sections on the subway map. I suspect they did not do this so you wouldn't realize how selective the coverage is. At the very least, the parts of Seoul which do appear are somewhat well covered, though the maps are still deceptive, as there are numerous side streets and alleys that do not even show up. Oh, well.
