I'm still trying to find a favourite pho place in my new hood, and, alas, nothing about Peach Garden blew me away.
The good:
big, lots of seating
fast, competent service
standard (but not great) pho prices (my small bowl was 6.99$ or so)
pho is fine
The bad:
the pho is just fine - fine noodle to broth ratio, fine selection of toppings - but the broth has none of the delicate and delicious complexity of any of the three pho places in my old hood.
The verdict: If you, like me, live nearby and occassionally find yourself in need of some hangover-curing pho, this place will do fine. No reason you should go out of your way to visit if that's not the case.
