Is a pizza like this unheard of in the USA?
There is a fantastically wide range of pizza styles available in the US. The traditional American &quot;fast food&quot; pizza, such as one would get from Domino's or Pizza Hut, has a fairly thick, doughy crust, but thin-crust pizzas are nearly as widely available, and have become more common over the past two decades.
In the US, it's less common for pizzas to be ordered by a particular well-known &quot;standard&quot; name like &quot;capricciosa&quot; or &quot;pugliese&quot;. A pizzeria will often have its own menu of topping combinations with their own names. Depending on the pizzeria, people might tend to order one of those, or they might be more likely to specify the full set of toppings directly, e.g. &quot;ham and mushroom&quot; (definitely not an uncommon combination, and one that would be available from virtually any pizzeria).
I've only had pizza in Sweden once, but what I had would not have been at all unique or remarkable in the US.
