This place has been reviewed a lot, obviously, so I'll keep it short and sweet with a list.
Pros:
The vegetarian Pho is amazing. I will only have eyes for it when I go there, and maybe a fresh veggie spring roll. Unlike two of the other reviewers who had some sour grapes over their experience, I have multiple resources that the veggie Pho broth is vegan.
Cheap. Huge bowl of Pho with fresh veggies and a drink for under $10.
Cons:
Parking in this neighborhood is a racket and restaurant doesn't have a lot.
Good to know:
No credit. Take cash, or use the ATM in the vestibule.
Atmosphere is hole-in-the-wall. If you can't cope with that, get takeout or don't go.
