Cheap, quick, hot, authentic Bánh cuốn.
For any Anthony Bordain fan, this place is a must visit in Hanoi. In my opinion, out of all food houses introduced in the show, this is the only one that successfully preserved the authenticity. And remembering that the show was on TV in 2011, an applause for the owners.
Note that there is not many parking lots, so walk or book a bike ride.
