Ironically, I feel like PizzaHut is now the most outdated of the pizza chains when it comes to web technology. I've been working on a fun project where I need to order pizza gift cards, and PizzaHut is the only chain that doesn't integrate with any gift card APIs.
Also, Domino's is way ahead of them when it comes to actually ordering pizzas online. Has anyone seen the Domino's pizza delivery tracker? It's awesome. It actually makes delivery feel faster by breaking it into steps.
