Don't let the dingy decor fool you. The food is amazing!!!
A friend of mine took me here a couple of years ago and this is my favourite Thai restaurant so far. They have the best Thai food in Toronto. It's pretty authentic from what I've been told.
I'm not usually a fan of Thai food only because most places that I've been to can't make a decent Pad Thai sauce without using ketchup.
My personal favourites are the Curries (red and green), Pad Thai and this other stir fry clear noodle dish.
I've never had problems with their service. The gentleman is very nice and quite attentive if he isn't running around serving other guests. When I'm in the mood for Thai, I usually come here when I'm in the area.
