This place is 200% authentic Vietnamese cuisine and dining experience (which isn't all that positive). You rarely will find anyone that's not Vietnamese dining here due to the abundant bigger name Pho restaurants (Pho Dau Bo, Pho Hung, I Love Pho) seconds-to-minutes away. This place is popular amongst the older male Vietnamese drinkers who will stay in the restaurant for hours late at night before heading home. This creates a rather sketchy, unpleasant dining experience, which is why I usually just order take-out.
The food here on the other hand can be great but often inconsistent. Since it is a smaller-run restaurant, they are often out of ingredients for 75% of the menu. Nevertheless, the rice dishes here are their strong suit, in addition to their family-style meals. Their smoothies are average (if they have the ingredients necessary).
Don't expect too much from the service either since the only time you'll see the one server is when she comes to take orders, and bring your meals; otherwise be prepared to flag her down if you ever need something.
Overall, an authentic Vietnamese restaurant with good rice dishes but the inconsistencies and lack of ingredients are hard to ignore. Otherwise, the attraction of older Vietnamese drinking audiences may cause you to consider either ordering take-out or visiting other nearby restaurants.
