Pita Grill, in my humble opinion, is one of the best donair shops in Calgary. It is a small space and the lunch crowd fills it quickly during week days. The ordering process is a bit funny, but it works.
The menu is varied ranging from shawarma plates to XL beef or chicken donairs. Be adventurous and get a "Mix" donair - totally crazy - beef and chicken together in same pita wrap! The sweet and garlic sauces are awesome as well!
This place is a "must try!"
