We dropped by for lunch and had the signature Chef Nuit's pad thai. it was quite good - tangy, flavourful and very spicy. It's probably the best in the downtown core -- but mainly because there isn't a lot of competition. Elsewhere in chinatown and further north has just as good, though. Service was a bit slow, but understandably given that the place was packed.
My main issue is that the place is VERY LOUD! Like a high school cafeteria, but noisier. We could barely hear each other and our throats were a bit hoarse afterwards having to almost shout our conversation. Definitely not a place for a business lunch to chat leisurely. Yelp lists the Noise Level here as 'Average', which is completely wrong.
