I go to Young Thailand at least once a week. My girlfriend thinks their Pad Thai is the best in the city and swears she could eat it every day and never get sick of it.
I tend to mix up what I order and have tried much of the menu, often getting the Pad See Ew or Thai Spicy Noodle, but I've never had a bad meal here and service has always been good.
The interior decor is really lacking, and mostly the reason for my 4 star review. I try to mostly go for take-out, but with friends will often sit in, and the atmosphere is just so lacking that it puts me a bit ill at ease. While service is good, there isn't much personality behind it (language barrier?) and I feel that might lead to a forgettable experience for some people.
That said, based on past experiences and how close it is to where I live, this is my thai staple in Toronto and I would definitely recommend it to anybody wanting thai takeout.
