For airport food you honestly can't expect much. Most places are fast food places, and their quality is usually lower than places not in the airport. Looking at the negative reviews for this place, I feel some people's standards might have been too high when they shouldn't really have set their standards such way.
Anyway, I chose Thai Express while waiting for my flight to Winnipeg, as I wanted some pad thai and not burgers/sandwiches. I will say though, service was extremely slow here. The time between me ordering and getting my food was about 25 minutes...that's not fast food.
As for the food...as I said, it's airport food quality. It's certainly not the best Thai Express I've had, but it's edible food that didn't get me sick. That's honestly all I can ask for.
