"I never go to the city," said Sara Pistorio, a 22-year-old Perry Hall resident, as she noshed on some French fries and ketchup Sunday at a street festival in Towson. She dreads looking for parking in Baltimore, so the suburbs are simply more convenient. Plus, she says, the options in her area have expanded over the years, particularly for someone who prefers a vegetarian diet, as she does. Among her favorites are the tofu options at Taco Love Grill and sushi at Chopstix Cafe. "It's so good," she said.
