There are so many good types of pizza out there that it's hard to pick just one favorite.  It depends on the mood.  There's this uber thin crust at a restaurant by home that comes with a spare amount of white sauce and mozzarella.  They add the prosciutto and arugula on it afterwards it bakes, soon enough to warm it a bit.  This is the place that uses wood fire pizza ovens.  It's simply amazing.  They have great normal pizzas as well.

A chicken barbecue sauce pizza can be good if done right.  So can a normal, meat-eaters pizza.

In the end, Jeff definitely has the winner:  Free pizza usually tastes the best because somebody else bought it. 😛
