Of all the Pho places I've been to in Chicago, Atlanta, and the Bay Area, this place had the best broth I had. It tasted SUPER clean and the thinly sliced beef they give is just rare enough that it's edible but not too chewy. Their prices are right on par (about $8 for a bowl of large pho) and they give lots of sprouts.
They are super quick which they should be. It indicates the broth is already made and they do a wonderful job even at 9 AM in the morning!
