To be fair I think pizza can (and will) be good everywhere there’s someone that learned how to make it… Which isn’t hard at all, by the way.
I had awesome pizza made by this Egyptian cook in Hannover and horrible pizza in Italy made by Italians.
Edit: also the only real test for pizza is this one :
If you’re thinking that you’d love another pizza right now, even if you are full - then that was a great pizza.
If you think that your definitely going to come back for another pizza - then it was a great pizza
