This may be the best place to eat at Terminal One, at least compared to the post-security transborder options. It is definitely far and away the best food I have had at YYZ.
Didn't try the shawarma, I'm sure it probably does suck regularly. YYZ is a terrible place to eat. But the hummus, eggplant and tabbouleh in the mezza plate were all not just good but delicious. And the za'atar mannakesh was also very good. Though the mezza plate came with a freshly fired pita (which was crunchy on the bottom and floury/pale on top, but perfectly serviceable) so perhaps not needed.
Cashier said everything is prepped in the kitchen onsite, downstairs, but by the Paramount chef. So guess that takes some of those food service conglomerate employees who destroy the other food out of the equation.
