This is a seriously impressive hole-in-the-wall mom-and-pop Vietnamese restaurant. The menu is very extensive (which I found exciting, after Long Phung on Detroit closed--which was the only other Vietnamese restaurant in town with a similarly large menu), and the menu has a number of dishes that you won't find at any other place in town.
The food here also has its own unique flair. It is not in-your-face in terms of how it is spiced: I found it to be more subtle and balanced, almost in the way Cantonese food is subtle compared to say, Szechuan or Hunan food. But it's really, really good. The ingredients are fresh.
The atmosphere is minimal. It feels very 70's/80's and the interior is a bit bleak and looks like it hasn't been fixed up in a while. But the prices are very low and the food is outstanding, so what can I say? Absolutely 5 stars.
