Despite the weird set up for paying for the food, I found the beef pad thai here to be alrightfor airport food. Conveniently located in the hub of all restaurants, this place is pretty easy to find within Toronto airport.
Before you step up to order and pay, make sure to see which cash register is active and working. I stood there for awhile confused at where to pay since the people around me didn't have any clue. Finally, I found someone who had already paid and she kindly directed me to pay at a different register that was across from the place.
Prices are a bit high, with majority of the items near $10 and the portions are so so. For the beef pad thai, it definitely was a bit saltier than what I'm used to but at the very least, it had flavor.
Would I stop by here again for food? Probably not since there are more food places in the area that seem to have better service and a short waiting time.
