One of my favourite Thai places in Toronto.
I love their pad thais but my favourite has got to be their Pad See Ew. The thicker noodles are great and it really fills you up. I usually get the medium spicy one for this as the mild is too mild. The medium pad thai is spicy enough but depending on your tolerance level, you might want to stay at mild. I myself have a decent threshold so if you can't handle spices, best to stay at mild and get some of the peppers on the side.
Also, their dessert is really really good. It's super sweet but if you're craving for it, definitely worth indulging on!
In terms of the waiting periods, best to go during lunch or later in the evening but not after 9/9:15. If you are in a group of 2, it's easier to get a table vs a larger group just based on the seating layout here. But I'm a big fan so definitely recommend!
