Correction - it is NOT in the Lucky Grocery.
It is a few stores East in the Northeast corner of the small mall on Mira Mesa Blvd and Black Mountain Road.

I was informed by the owners and cook, that the cuisine is from the Northern part of Vietnam near the Chinese border, which gives it a slight variation (of better flavors in my opinion) to the other Pho shops.
There is enough similarity to all the other PHO shops along Mira Mesa Blvd, that I have eaten at to be called PHO! Except they do it best ! ^
