I believe this place is brand new. It branches off from the other location at Warden/Eglinton, I do believe they have another location else where.
The only time I go to Pho Saigon is when I'm on lunch at work, and am craving Vietnamese food. If it were my own personal time, I wouldn't touch this place.
Pho Saigon isn't the worst, but it's not the best. It's honestly very in the middle for me.
With the wide array of super awesome Vietnamese food in the GTA, this one rids of the craving, but you could get better for the same price range.
There isn't much I have to say about the place. It's just regular Vietnamese food. If you're looking for something a little more tastier, I might suggest Pho Metro or my favourite one at Pacific Mall, Tam 168.
