I have tried many, many pho restaurants in metro Vancouver. Most of them are average, and only a few warrant coming back. But this out of the way little place on the second floor of a building in a corner of Chinatown has become my favourite cure for pho addiction. (I agree with the previous reviewer: the name on the sign is Pho Le Inc.)
To compare the different Vietnamese restaurants, I always order rare beef pho on my first visit. If it's good enough, I pay more visits. Usually though, the quality of the broth can vary from day to day. But I can say without a doubt Pho Le consistently has the best pho broth. I once took someone who had an MSG allergy here. I asked the server if there was any MSG used, and he said they only used bones in the soup, and that the way to tell if there was MSG was to see if you became very thirsty after eating. True to his word, my friend didn't develop any allergy symptoms, and unlike most other MSG-laced pho places which have you gasping for water half an hour later, we didn't suffer thirst afterwards.
I've seen a few different servers here, and the service is always good. For some reason they are never busy, and I always got prompt and polite service. Ambiance is slightly better than other Vietnamese restaurants since they are on the second floor, and I could always get the window seat. If I happen to drive by, my pho addiction meter always goes crazy, and soon I would be sitting by the window, having the best pho in Vancouver with a smile on my face. It is that good.
