It seems this bar is the favorite place of Korean people who visit Hanoi
Chilled bar with cheap price in the middle of the famous beer street. If they don't have any special event, you'll need to pay only 100.000 for the entrance ticket (included one drink).
Its space is quite small but usually crowded. I wonder why there are so many Korean guys around whenever I go here. It seems this bar is the favorite place of Korean people who visit Hanoi. Haha.
