Query: Yellow Pages for a foreign resident

Laid out alphabetically by subject, this book is of some help for the English-speaking foreign resident of Seoul or its environs. Much more detail would be helpful, as would at least one map of the city itself. Even directions of how to get to places are too general.There are many better resources for the expat in Korea, including basic guidebooks of Korea, The Expatriate Handbook does, however, have a niche and will come in handy at times.
