You have plenty of options for getting where you're going.
The Pearl is in Fareless Square, which means you can hop a bus or the streetcar and ride downtown or to the Lloyd Center across the river for free. Good price.
Stop in to nearly any retailer in the neighborhood and ask for a free walking map of the district. They include restaurants, shops, galleries and more.
