It's not hard to find Middle Eastern food in the UofT area, yet for some reason I'd always come back to Momo's. It's closer to the campus than Ghazale, much more authentic than Pita Pit, and a nice enough place to go with a group.
I always got the hummus - whether I'd accompany it with falafel or salad or just have it in a sandwich. The hummus isn't the *best* I've had (okay, well, I grew up on Israeli food, so I've had some flippin' good hummus) but it's still solid. They top it with some olive oil... mmm. Get extra pita, which they'll char on the grill for you.
There's outdoor seating, but given that it's Toronto, it's only open a few months a year. The inside is understated and cozy. No-frills tables and chairs, and open kitchen if you sit towards the front. The staff is always nice and generally unobtrusive. Prices are decent too.
I'm a fan!
