We ended up at the Tin Pan which was packed with Americans and other internationals. It offered loud, good clubbing music. Bars in Korea don't close and so we ended up staying out until 4:30am!
Because of the weather, none of the cabbies wanted to take us all the way back to Gimpo. We were finally able to bribe one in to taking us home to the tune of 50,000 Won. Ouch!! Why, oh, why don't the subways run all night!!!
