I haven't hit up all of the gyro spots in Pittsburgh quite yet, but Olympos Gyros has been my favorite gyro since my first visit. I always get an original or a Zeus if I am in the mood for fries. Their tzatziki is delicious, and their gyros are always overflowing with filling. Plenty of meat and plenty of toppings. Their baklava is delicious as well. I drive from Pleasant Hills just to eat there, even if I have no other business in Robinson. Worth the drive every time!
