Postino's is one of my places to dine in AZ. The bruschetta is the best I've tried. My personal favorites are the brie+apple+fig, warm artichoke, burrata+arugula+bacon, and ricotta+pistachio. The soup of the day is always a good choice to pair with the bruschetta.
Decent happy hour prices and can't beat the Monday and Tuesday wine+bruschetta deal.
