[Worst pizza I ever ate was at Shakeys in Tokyo.
The on in Rome was a close runner up!]
Having said that, even bad pizza is, well, pizza. It’s basically a bread dough, tomato sauce, Italian spice mix and cheese baked in an oven. Hard to really screw that up. Even bad Shakey’s isn’t all that bad. But it’s probably an indication of how far it’s strayed from what we consider pizza that close to 90% of its outlets are located overseas:

Next I stood in line half an hour to see what Marxism could do to street-vendor pizza. It did not disappoint. The word cottony is sometimes used to describe bad pizza dough, but there is every reason to believe this pizza was really made of the stuff, or maybe a polyester blend.
The slice-- more accurately, lump-- had no tomato whatsoever and was covered in a semiviscous imitation mozzarella, remarkably un-chese-like even for a coal-tar by-product. Then there was the sausage topping. One bite brought a flood of nostalgia. Nobody who's been through a fraternity initiation will ever forget this taste, this smell. It was dog food.
