We've been coming to this location of Pho Mi 99 for a few years. It's fairly comparable to the other locations although I'd say the Mississauga locations are consistently better (food and service).
It's located in a plaza right next to Vaughan Mills Mall, so it's really convenient if you want a Vietnamese food fix before or after you shop.
Our favourite dishes are the #113 (tasty, clear broth with glass noodles, assorted meat and seafood), most of the pho choices as the broth is tasty and #414 (vermicelli with grilled meatballs, shrimp on a sugarcane and spring roll). Also, try the iced Viet. coffee with condensed milk. It's awesome.
I definitely wouldn't hesitate recommending this location of Pho Mi 99 for a cheap and cheerful Viet. meal. Prices are great and the place is clean.
