My rating is for the gyro only. Yanni's is located in a non-descript neighborhood strip mall. On to the gyro: The owner explained to me in great detail how they use authentic ingredients for the tzatziki sauce and how they ship in the pita bread. Hey, do whatever you need to do, but keep those gyros coming.
In summary: I've been on the hunt for great gyros for over twenty years. This joint hits all of the marks.
