Being just down the street from Salad King (being known for big portions of edible faux-Thai food and not much else) and being close to Ryerson, we weren't sure what to expect from Thai on Yonge. But it's now my go-to for Thai food in the area (not much competition, but still...).
The prices are about the same as Salad King and the portions are smaller - but the everything we've had actually TASTES LIKE THAI FOOD.
It replaced a crappy Chinese restaurant which probably replaced a crappy diner (which had a long bar for some reason), so the decor sucks. And it's definitely not a trendy spot like Salad King -- but the food is good and you don't have to rub elbows with strangers in the cafeteria-esque dining room at Salad King.
But ya, excellent flavouring on everything we've had. Brought a miserly friend here who is all about food portion over price and even he felt Thai on Yonge was a better bang for the dollar.
