Yes, I have eaten pizzas in New York. not sure what style it was though but it looked pizzish.
As I see/understand it Hawaiian style can be New York style. Now, I'm not sure exactly what New York style means and how it became the New York style in the first place, but from my perspective it looks a regular pizza. Add pineapple on top and you are golden. What kind of styles do we have? New York style? Pizza Hut style?

But the best pizzas is the one you make yourself. priceless! Will add spinach next time!

Edit: I think we have had a great pizza discussion earlier in this thread but I don't remember the outcome so I think this one is valid. It would be great with a World Cup Pizza competition. Every Country has/have to vote for their best then ...The big final!
