I have visited this mall millions of times and have never even noticed this restaurant, because it is out of sight from the main parking lot. It was my loss.
I came for lunch a Friday upon recommendation of a co-worker who loves Vietnamese food. The place was full with both Asians and non-Asians customers. I figured that 1) this place was popular and 2) the portion was big. I ordered a Bún bò Hue ($8), which is described in the menu as a rice noodle that contains beef, pork and Vietnamese sausages in a hot and spicy Hue style soup. The soup base was sweetened spicy with a herbal flavour, but it was not that hot. Compared to a spicy noodle I got at Pho Mi 99 in Mississauga, this one was less spicy (the other one "almost" blew me away). I guessed this level of hotness was more acceptable by most anyway. The meat was plenty and good. I noted that it had more noodle than a small sized pho. The texture of the noodle was okay but on the soft side.
Considering it was a packed lunch hour, the food came out quickly. I would not go as far as describing the service as friendly, but it was definitely efficient. This place operated like a well-oiled machine.
This is an authentic Vietnamese pho place. The storefront is clean. I will consider coming again for a quick lunch.
