I am always a fan of Northern Thai cuisines, and was very happy to scout one in Toronto during my visit.
Although the restaurant could seat 200-300 (my guestimate), it was already fairly crowded at 5pm when we entered. We were seated right away in a large table sharing with two other parties, but all the parties were far away enough to allow relatively private conversations
We ordered green curry and the Northern Thai traditional coconut curry noodle soup (khao soi gai) - both were yummy, authentic, and above all, very fairly prices :)
