I consider myself a pho addict. If I could eat it everyday I would. I am from overseas and where I'm from you can get cheap Pho pretty easily. I have also eaten it in Vietnam and fell in love with it there. Unfortunately since moving to the USA I have yet to find a great Pho and was pleasantly surprised when I came to Co Do for a warm Pho on a cold day. I honestly picked it because it was the closest place to where I was staying during a quick trip to Calgary. I can say hands down it the best Pho I've had so far in my time in North America.
Got the original rare beef Pho and it was exactly the right flavours. It wasn't a big as some of the bowls I've become accustomed to but its a good size to still fill you up without making you feel overly uncomfortably full. Only down side was they did not provide any fresh chillies on the side with the spouts, lemon etc so I had to ask, but not a big problem.
Service was very good (better than the usual places I go and I actually normally find that the worse the service the better the food in these places so props to these guys for giving you both!). Also in terms of cleanliness (which others have said wasn't up to scratch) I would have to disagree with those people. The décor is really nice much more than your usual cheap viet place and it was clean and I didn't feel the need to wipe my chopsticks with a serviette which I often feel I need to do at other pho places.
If you are nearby, highly recommend!
