I've had anchovies on my pizza for years.
I like classics: most of the times it's just tomato sauce and mozzarella cheese. Sometimes I add some sort of cured meat (ham, dry-cured ham, bresaola, ect) or veggies, but not that often.
I have never tried the one with pineapples and, I admit, I am not sure I would like to.
I also must disagree with Tano, a couple of comments above. I know a place where they bake an amazing "pizza al taglio" in their wood oven ;-)
