Meh, it's Osmow's.
It's definitely still a shawarma powerhouse considering the long lineups, but I think their food could benefit from cooking their chicken a little more, using fresh pitas, and not overdoing the sauce as a default.
However, it's unlikely that Osmow's will make any changes as they continue to expand at an impressive pace.
Decent food, it's just not for me. I prefer Pita Nutso or Pita and Grill in the west GTA.
