I recommend the vermicelli bowls! Portions are pretty big and it only costs $8.50. You get to choose your own toppings (3 choices). Price is one of the cheapest I've seen for vermicelli bowls! Especially for the size. Note that the vermicelli noodles are thick though, and not the regular thin ones that usually comes in these bowls.
I also tried the bun bo hue. Very flavourful but Beef did not seem to be the highest quality :( Still a good bowl of bun bo hue though especially since there's not many good bun bo hue options in Markham!
Ambiance is nicer and feels more high-end than other pho restaurants.
