I've eaten at this particular Pho 99 quite a few times in the past. The quality ranges from superb to slightly above average. At times the pho comes out piping hot with nice firm noodles and meat that falls apart in your mouth. Other times the pho comes out luke warm with soft noodles and tough meat. The broth has never been bad however depending on the time you either get a mild tasting almost clear broth, or a very dark slightly salty quite flavourful broth.
The best pho I have ever eaten came from here, but only once out of many trips.
Their rice dishes and rolls are worth a mention as well, my wife orders them every time, and I've yet to have a bad dish.
The service is on par with the vast majority of pho restaraunts, you need to flag waitresses down for water, forks and small bowls for children are offered occasionally.
They do not try to exude any special ambience, It's just a place to come and pick up a cheap lunch or dinner. However, it does seem to be one of the cleaner pho places i've been to.
As for value, I am not a native vancouver resident so i do tend to rate the value of the food higher than most as your prices tend to be amazing. However how can one compain about taking your family out for a decent meal that runs you under 20 dollars all said and done.
