"The hard part about the pizza business is consistency and staff," says Tung. "Who is on the oven? Who is making the dough? Is it going to be consistent? Al's is always consistent." We ordered a sausage pizza. The cracker-thin crust was like a shard of gypsum crystal, crackly and flaky, yet strong enough to hold back the molten lava of well-seasoned red sauce. "The sausage is so flavorful, like little pinches of meat spread evenly over the pie. It's one of the best sausage pizzas around." As you pay up, witness the charming tradition of the cashier imploring the pizza crew to "say thank you, boys!" Thanks erupt in unison as you step back out into the noonday sun. 28W241 Warrenville Road, Warrenville, 630-393-9630, www.alspizzainc.com.
