They’ve been doing this for years and years. The pizza isn’t bad, but they cut it into little squares, which I personally don’t get.
Easier to eat in hand. Those big triangles of round pizza flop all over the place, and you have to fold it over to eat it without getting hit by food shrapnel. Also, if you're feeding children, little squares make it easier for little hands to hold, and less is wasted, because they're eating smaller pieces, so they don't take a few bites of a big piece and leave the rest. Bigger folks can just eat more little pieces. ;o)
