There are quite a few places that serve the soup, and many of them quite good, but I generally go to Mr. Phở. Located in the Super Cao Nguyen Center (the large glass and brick building attached to the Super Cao Nguyen Supermarket) at 1133 NW 25th St, this shop is always busy at lunchtime.
Two entrances: inside & outside the Super Cao Nguyen Center
On the left, delicious phở; on the right scrumptious mì.
Prices here are very reasonable, and most of the soups are available in three sizes (the pictures above show the large, which tends to be enough for my lunch). In the background of both images, you see the plate of herbs... sometimes they give you saw-tooth herb (Eryngium foetidum). ^.^
There! You've no excuses not to visit!
Many appologies if my computer refuses to use the correct characters. And again, I have no affiliation with this shop (besides the fact that I eat here quite often indeed).
