This is an incredibly beautiful setup, but, I can't help but think that there might be some things he overlooked.
Like the oven. As John stated, for a guy that's so aesthetically driven, he should know to point his oven towards his customers so they can see his fire. The flame is, by far, the prettiest part of any pizzeria. I know he's not dealing with a lot of real estate, but, that, to me, should be the first aspect of any design.
Also, I like the egalitarian theme, but does this mean he's going to be descending/ascending stairs to get people their pizzas? Or is he having his customers climb stairs? Manning an oven can be pretty strenuous, but manning an oven and climbing up and down stairs? That sounds a little masochistic to me. And if he's having customers climb, that puts them right near him/his oven, which is a recipe for many kinds of disaster (accidents, theft, etc.).
And then you've got the size of the truck. Maybe in San Fran there's enough space for big rigs to get around easier, but here in the NE, the height and turning radius would be a tremendous hassle. I know that a Ferrara is incredibly heavy, but I can't help but think that this might fit in a smaller, more drivable truck.
Don't get me wrong, I'm still incredibly impressed. Ferraras on trucks is not something you see every day, so this guy is tackling uncharted territory and I give him a lot credit for that. But I can't help but think that this thing is a little too pretty and not quite utilitarian enough.
Btw, this is San Fran, right? This rig has got to be making Casey a little nervous
