We always travel all the way here from Markham every time we feel like bun bo hue. It's definitely worth it! The portions are good, and you will never leave on an empty stomach. The food comes out quick, the soup has a good amount of spice, and is definitely flavourful. This is the only pho place I know of that has more than 1 size for bun bo hue.
There are many seatings, super casual. It's cleaner than most pho places, 4 stars because we always get the bun bo hue and yet to try anything else! It's cash only so bring cash!
