Seriously the Banh Mi is horrible compared to Nguyen Huong. This place mainly specializes in Che (sweet soup...not pudding.)
My favourites are:
Che Ba Ba (banana, sweet potato and cassava drowning in coconut milk)
Che Dau Den (black bean)
Che Dau Xanh (mung bean with seaweed)
and Che Ba Mau (three colors..actually forgot what's in it)
The banh bao (steam bun) are also pretty good for the price. They're nice and big so you actually stay full after consuming that monster of a bao.
