We live nearby and I've had take out from here once but we recently decided to really sit down and try Thai On Yonge.
The decor of his restaurant isn't very fancy and you'll need to go up some stairs but it feels a lot like Thailand which makes it nice.
We ordered the mango salad, lemon grass soup, tamarind beef, and pad kee mao. Woah! Everything was extremely flavourful! The lemon grass soup, salad, and beef definitely packed a punch. Sometimes it was overwhelming but everything was really good. The ingredients were fresh and well balanced in all of them. You can see how colourful everything is in the picture. The mango was ripe and the beef was crispy. The noodles were tasty too- a little oily. The food was very authentically Thai (coming from someone part Thai) and the people working there are Thai. If you go here then I'd recommend trying things on their menu other than pad Thai!
Pleasantly surprised- we'll be sure to come again when we have a craving for Thai food!We also noticed on our way out that they have boat noodles which we'll definitely be back for :).
