I'm not sure what to think. One of my favorite pizza places offers some profoundly strange pizzas which stand up well on their own but if the ingredients were offered separately, could be quite disgusting. They make a great reuben pizza with a sauce of thousand island and a touch of sauerkraut in it and a great greek pizza with pesto sauce, feta cheese, marinated artichokes, and pine nuts sprinkled on top. Those toppings work well together, but I shudder to think of what would happen if some of those toppings were offered separately. An app that discourages you from ordering a pizza with thousand island sauce, sauerkraut, pepperoni, and feta cheese might be a very good thing.
I tend to prefer specialty pizzas to the ones where you just add standard toppings. There are way more interesting options that way. I had a fantastic fig and balsamic pizza when I was travelling. Never would have thought of it and now I want to make one. firopizza.com/menu/signature-pizzas/ Primo: Gorgonzola, Artisan Cheeses, Smoked Prosciutto, Balsamic Drizzle, Fig Drizzle, Shaved Parmesan.
most of the places around here offer specialty pizzas, but you can still always pick your own. I usually end up tweaking a specialty - add some bacon and jalapeno to a BBQ chicken pie that already had red onion included, or leave the olives off a veggie lover's pie.
were they a really small shop that probably couldn't handle going off script?
