131 - actually in love with this dish.
Mistakenly ordered 125 thinking it was THE bun cha we wanted. Got this noodle in tomato soup-looking dish. Tasted horrible. I saw others eating this and I am sorry, but I could not understand... how?!
After getting the wrong dish, we ordered what we came for. Number 131, under the section with a bolded word BUN KHA. Uploaded photo of the menu for your reference - you're welcome.
The dipping sauce/soup is vinegary and you get a heaping amount of noodle that you dip into the sauce. Simply amazing!
