After trying Nino and wanting another to compare, finding a good gyro was actually much more difficult than expected in Greece. I tried to go to Pitta Pappou but the staff pretended I didn't exist when I stood in the door trying to speak to someone. There was also Soflaki in an alleyway but it was closed every single time I went past (which was quite often).
Although not really a gyro place, gia has skewers and rotisserie chicken. I didn't have the stomach space to eat everything, but they were kind enough to cut off a piece of the chicken for me to try. Really delicious. I would go for that (kontosouvli) next time there.
Instead of this occasion I tried the Mix souvlaki €7. Chicken kebab was very tender but less flavour than the spit version. Pork skewer was nicely charred and had decent flavour. Sausage pork was quite salty but alright.
Cheap prices and friendly people. I would definitely have gone back if they weren't closed on the Sunday that I tried.
