Jeju Island is an hour away by plane. There're about eight casinos concentrated on a small island. I took a picture of a sign advertising a new casino in Jeju. It's called Beluga Casino located in the Jeju Shilla Hotel:

I don't have many chips from this Island. One day I'll make a chip run there.

Have fun! If you need any info about South Korea send me an email.
