Khao San Road is the best thai food in town. I moved from San Francisco where there's a thai restaurant on every corner and I was truly disappointed with the thai options in toronto, most of which overdid the coconut milk part making the food sweeter and unhealtheir.
We had to wait for long for table at Khao San but it was worth the wait.The pad thai was very good with a right dose of tamarind. It got too crowded in the waiting area but the owner/chef/floor manager offered people free bites. He also came across and casually chatted about the food and service. All in all, I liked the food, the ambience, the communal seating up front, the location and the service. Five star for sure.
