My favourite pho in all of Toronto, including the GTA.
The owner and all the staff are very personable, service is quick although there can be long wait during peak dinner hours (but that's the sign of a great restaurant).
The restaurant itself is extremely clean though it is not very fancy and some of the seating is quite close together.
The green tea is freshly brewed, their fried spring rolls are always a hit however if you take them home they will lose their crispness.
My go to is the grilled chicken pho (sometimes I'll add extra rare beef) or their rare beef. I usually stick to a medium.
Portions and prices are extremely reasonable and on par with most other pho restaurants (maybe a few cents more but again the quality is great).
It's worth the 30 minute drive over from North Markham.
