I love Paramount. It's the best Middle Eastern food I've had in Toronto and it's a great option near the Eaton Centre. The fact that I always hear more Arabic than English being spoken at the tables around me lends even more credibility.
The pitas come fresh from their wood burning oven as do the zatars. The chicken shawarma is amazing, the hummus fresh, the soup is great too. Every time I go I try something new and so far I've been very happy. The only thing I didn't particularly care for was the labneh but I was never a big labneh fan to begin with.
The decor is cool, it seems to be in an old stone house with a pointed roof which you would never guess from the outside.
The only drawback, and it's a big one if you're in a hurry, it Paramount's popularity. It's always packed and you can expect at least a 30min wait for a table if you go right at lunchtime. The poor servers, while they do their best, are running around like crazy trying to keep up with the demand.
I've been many times, and will continue to go anytime I'm in the neighbourhood.
