Ask the taxi driver to take you to 29 Hang Mam,Hoankiem,Hanoi on the corner of Hang Bac and Hang Be St and Hang Mam St. If you are facing the Hoan Kiem Lake from the front of the square Hang Mam will be the street to your right. Travel up the street for 600 meters and we are on the left hand-side. Look for the SHARK!!
