There are several Pizza Rocks throughout Taiwan.

I went to the recently opened one in Yonghe district, Pizza Rock 8.
The pizza was better than I anticipated, and was more American-style thin crust
than Italian-style (less tomato sauce) or Taiwanese-style (like kim chi or mayonnaise pizzas).
The minestrone soup was ok.
I will return to check out their pasta dishes in the near future.
