TOP PIZZA: Standard by definition but certainly not by taste, the Margherita harmonizes California canned tomatoes, house-made mozzarella, and basil. Parents of young children, take note: this natural palate-pleaser is suitable for even the pickiest eaters. BOTTOM PIZZA: Mezzo’s Pistachio Pizza is not for the faint of heart. Rich and filling, but not too heavy, it starts with a saucy mixture of toasted pistachios and olive oil, followed by porchetta — a type of rolled-pork belly — which is lightly cured and seasoned with fennel pollen. It’s all topped off with a fresh arugula salad.
