Head to Hang Manh or Le Van Huu street where grilled pork patties and vermicelli are served tableside with fresh herbs and dipping sauce. Obama famously ate this on Bourdain's show.

Catch an early bus from Luong Yen bus station or book a minivan through your hostel to reach Ha Long Bay by 9 AM. Focus on the free areas around Bai Chay or the Tuan Chau Island promenade rather than paid cruises.
