If you walk into this North Highland pizzeria and there’s a sweet 16 birthday dinner going on, don’t worry about it. Families love pushing tables together for group gatherings at Osteria 832. And with its lineup of quality pies, pastas, and salads for reasonable prices, you can’t really blame ’em for wanting to eat here. But even if the only thing you’re celebrating is making it through another workday, consider the tender fried calamari a small present you unwrap with every bite. Still, the best gift is a charred, thin-crusted pizza that’s sturdy enough to hold the generous amounts of mozzarella, mushrooms, and other toppings.
