and it keeps getting better

BTW, I've eaten pizza made with lava rocks from other places (Mt. St. Helens, some underwater volcanos) but nothing compares to the flavor of authentic Italian lava rocks.

Im-a from Italy and this pizza is delicioso just like Granny used to make. The cheese is a delicate explosion of flavors while the crust is crispy like a falling leaf on a cool autumn day. The SAUCE is the best, just like the RAGU uncle paulie used to make in sicily.

The lava rock was brought from Mt. Vesuvius for that authentic italian flavor.

I was initially attracted to magma by its lava oven gimmick and boy do I feel cheated. Not only was the pizza an over priced slice of ellios (ellios taste better by the way) but the thin lunchables style pizza was so boiling hot that I had to wait a good 10-15 minutes for it too cool down in order to avoid a trip to the burn unit. I guess that is what happens when you cook in a fake volcano.
If you really want a slice of pizza cooked near a volcano I suggest you go to Pompeii and order a slice because Princeton NJ is not the place to find it.
