I ordered the bun bo hue and it is plain. I have been here before for the pho and the portions are small considering the price.
My reasoning for the low ratings is also due to the staff who only speak Vietnamese with each other. As someone who understands Vietnamese, it is annoying to hear the staff talk about customers in their own language.
I wrote on the order sheet that I did not want onions or bean sprouts. I later heard the staff complaining about my request & saying in Vietnamese that I am "difficult".
Do not come here if you want good portions or good tasting pho. Staff are also very gossipy in Vietnamese.
