"Noraebang" is Korean for "karaoke room." We teachers went to one following a joint welcome/birthday dinner. Jake and I teamed up for a Korean boy band song (Ring ding dong by Shinee) and Adam and Jake regaled us with some classic American boy band tunes. We think Jake was in a Korean boy band in an alternate universe.
(By the way, soju and salad do not a dinner make. Just trust me on this one.)
