I was recently at ARZ bakery on Lawrence Ave and had not eaten lunch so decided to walk over and find something at the strip plaza just to the west of it.
There were a few choices including a few Sri Lankan places in that strip, but the windows on a few of them looked like they hadn't been cleaned for months so I decided to try Nasib's as it appeared quite clean. The menu indicates they have both beef and chicken sharwarma at $4.99 each. They also have a deal where for $5.99 you get two shawarma. I ordered one of each and ate the beef one there. It was really tasty. There are various toppings that you can select from to add to the sharwarma, including red cabbage, hot peppers, parsley, onions etc.
When I got home, I split the chcken shawarma with my wife, it was quite good but did not have as much flavour from the marinade as the beef one did.
They also sell various salads and falafel. I'll go back next time I'm in the area. They would do well if they were in the Greektown area. It seems like a better deal than the burger place that just opened at Queen and Broadview.
