I've visited several of their locations and this one is by far the weakest. Other locations are typically known for getting good value. Unfortunately, this location is overpriced and the portions are really small.
First visit, I ordered a regular Pho which was served in a tiny bowl and contained broth, noodles, and some beansprouts, thats it. I gave them a second chance, and tried their butter chicken roti (yes, I dun goofed ordering roti at a Vietnamese place) and it was not only small, but contained half potatoes, and a handful of "butter chicken".
Unimpressed. Stay away.
