A fresh option for lunch or dinner is Bun Dau. Literally translated to mean ‘noodles and tofu’, this favourite Vietnamese street food option is truly worth trying!
Bun Dau can be easily found on the streets of Hanoi. To find it look for people huddled around big round colourful serving trays with plates of write noodles (bun), fried tofu (day phu), fried fish cakes (ca ?), spring rolls (nem), and a pile of lettuces and fresh herbs.
To eat it, take a choice of dips - either a traditional shrimp dip (mam tom) or sweetened fish sauce (nuoc mam) - and dip your noodles, tofu, fish cakes, and spring rolls into it. In between bites take bites of the different lettuces and fresh herbs creating new flavours and refreshing the palate.
Cost of bun dau can range from 25,000 VND per person up to 70,000 VND depending on how famous the vendor has become in the area.
A secreted spot in the Old Quarter to check out while on your Vietnam tour is on a side street, just off of Hang Da, exactly opposite of Hang Da Galleria, about 50m down. The women and her husband who run the little street spot are only there for lunch. Best to get there early, before the noon lunch rush or you’ll be waiting a while!
