I am a big fan of Thai food and have travelled to Thailand so I know what Authentic means. I can tell you that La Colonie Thaï offers a vast and authentic menu. The decor is beautiful, the quality of the food is top notch, and the service was very welcoming! Price is very reasonable for a BYOW. Through my conversations with our server who happens to be the owner Suk (not sure I spell it right), I can see his passion and his dedication to his business.
As for the dishes, my husband and I ordered the Tom Yum and Tom Kha soup, and we shared a papaya salad, fish cakes, Pad Kee Mao and Red curry with duck. All the dishes were so flavourful! I feel that we've travelled back to Thailand! We finished off with the delicious and authentic mango sticky rice. Seriously, we really enjoyed all the dishes we've ordered. If I want to be picky, the only thing I would complain about is that the beef in the curry was not tender enough.
I'm so glad I've discovered La Colonie Thai! It's definitively the best Thai restaurant in the South Shore, and one of the best ones in the Montreal area! Can't wait to go back and try some other dishes!
