Having read some of the other reviews, I think your experience will vary depending on what you order. I've been to Tay Do many times over the years and have always ordered a combo meal of grilled meats, which comes with a small house soup as a starter. I can definitely recommend this meal option as it is very tasty and almost as good as some of the other "more authentic" Vietnamese restaurants in Montreal. Bonus points: this restaurant is BOYB.
