Lately I've been studying Korean at the PNU branch of KLIFF (Korean Language Institute for Foreigners). The classes there are excellent and tonnes of fun!
Often before class or after I've been dropping by one of my old favorite haunts : Chabatgol Teahouse. It is easy to get to:
Just go up the street as if you are walking up to Pusan National University's main gate. Up ahead you'll see the NC shopping mall on the right. Stay on the left side of the street and keep going up the street.

 Next you'll come to a GS25 Convenience Store and a narrow alley next to it. Take that left alley:
 At the end on the 3rd floor there's Chabatgol! On the 2nd floor there's a Pool Hall.
 Aha! Here is they're menu to study. Any questions? Post away on this blog or @Busan Tea Cozies on Facebook.

 Since the last time I'd posted they've changed their decor a bit with some calligraphy drawn by Beomosa monks and new lanterns over the lights. They are open every day from 10:30 am to 10:30 pm!
