For $6, you can choose from any two of the following: Turkey Gyro, Roast Beef Gyro, and Greek Gyro.
All three gyros feature a warm flatbread filled with lettuce, tomatoes, red onions, tzatziki sauce, Greek seasoning, and either sliced turkey, roast beef, or gyro meat (a blend of ground beef, ground lamb, and Mediterranean spices).
They normally cost $4 or more in my area.
A company rep told me previously that they plan to rotate different "two-for"-type deals every few months or so.
