The nightlife scene in South Korea

Hi. I have to got to say, you really know how to write a question. lol. I have been living in Korea on and off for the past 18+ years. Korea has an excellent variety of evening activities and the Koreans love to party as much as others do. There are dance clubs, bars, restaurants, soju tents, (but these are becoming scarce) and lots of places to get amazing street food. I tend to stay away from areas like Iteawan, although there are a few good places to go there and I do drop in once in a blue moon.
  I think most places are relatively safe and there are venues that you caa attend to ensure you are in good company. There is an upcoming musical festival in HBC (Haebongcheon) where local musicians go to show off their skills in the many bars in the area. I think you can find it on FB if you search HBC. I'll be going this year so you can contact me at [email protected] if you want more specifics.
I live in Songtan. There's a place called Shindong shopping center right outside of the Osan Base main gate that has about 85 or slightly more bars, where you can find some good fun. Many bars offer pool and darts as well, and are free to play, unless you play electronic (soft-tip) darts, then its a few thousand won for a few games. In the same area you can also find a decent variety of restaurants, coffee shops, clothing stores, tailors, bag shops, and hotels, etc. Most of the people you'll find there are Westerners, so you should find it easy to communicate and find a nice place to chill. Hit me up at the above email if you have more questions.
Until then, take care. Dave
