I learned alot from listening to Korean Survival Phrases.  One of the most helpful tips is access to the Korean/English Tourist Hotline.  These people can answer anything and I mean ANYTHING you’d want to know about Bundang, Seoul or other areas.  I’ve used this number to all sorts of ways…To get bus information (especially if I’m lost), movie times, restaurant information.  They speak English perfectly and they’ve got all that information at their fingertips.  So if you haven’t tried it, you should.  Remember  02-1330.
