One of the biggest differences between the American and Taiwanese Pizza Huts was the menu.

For me, one of the most recognizable pizzas on the menu was the "Double American Sausage" (pictured on the left), which reminded me of a classic pepperoni pie I'd get in the US.

However, it was notably lacking in sauce compared to the Pizza Hut pepperoni pizzas I can get in the US (pictured on the right). It was also much crispier and the pepperoni was baked into the cheese instead of just being placed on top.

After trying this pretty classic pie, I decided to see what else the menu had to offer.

In the US, Pizza Hut allows customers to build their own pizza and customize it from crust to toppings. In Taiwan, the menu doesn't allow for many substitutions.

The most I was able to do is order one of the standard pizzas and add or subtract an ingredient or two.
