I thought I'd post here first since this is where I found this messageboard (via Google). My pho experiences so far
-Pho 75 (on Wilson) - I've tried it once, it was pretty good but I didn't think it was amazing.
-Pho 88 (West Broad St, Falls Church) - I had this last night for dinner. Tasty, large serving sizes, and very friendly service. My wife enjoyed it a lot. We will go back.
-Eden Center - I forget which place it was but it wasn't the one listed in this thread. It wasn't a specialty pho place. Very ordinary.
-Froggy Bottom - I can't believe someone mentioned this place for pho! I haven't actually tried it tho I've had several of their menu items and their "salad + pizza bar" many times. We go there for cheap beer (at the expense of a good meal) for Friday work lunches when we're not organized.
