Green line 2

There are some stores which sells electronics and sneakers. Most of the clothing stores sell women's clothing, handbags etc. Not a lot sell men's clothing. Hope it helps.

For me, I bought a lot of clothes in Gangnam underground shopping center. Im a huge shopper for clothes everytime I travel and i didnt expect that clothes in Gangam underground can be very cheap. Also, you might also want to try OPM shopping center in Dongdaemon. I love the clothes there esp office clothes. There are also shops in ehwa and hongdae. You can try those. Enjoy shopping!

Express Bus Terminal on lines 3, 7 and 9. from Myeongdong easiest to ride line #4 to line #3 and then to destination.

I never saw any signs but usually stores open till about 10pm.

This underground shopping street is not very big. When you exit Gangnam subway station, you will see it. It does not extend to another station.

Mostly 10,000 won.some are with higher prices. They don't take USD. Only local currency.. Hopefully it helps..

Lots of women's fashion starting from 10,000 won (abt $8.80USD based on the current exchange rate). Local currency only. Don't remember seeing a money changer there so bring cash. Money changers are difficult to find in Seoul other than main tourist area like Myeongdong
