More of a 3.5 - I'll have to go back (which I will) and try it again. I had the spicy beef pho, which was worlds more flavourful than your run of the mill Vietnamese restaurant (i.e. the place across the street).
The prices aren't amazing - their fried rice/noodle dishes are downright expensive at around $12, and their condensed milk coffee - always a favourite - is an unjustifiable $4. The main dishes themselves are more reasonable at around $7-8.
