Take a cultural journey into one of the largest Chinese quarters outside of Asia. Start at the green-and-ocher gateway (a gift from Taiwan) at Grant Avenue and Bush Street for a tour of herbalists, souvenir shops, restaurants and jewelry dealers. The narrow, crowded streets and alleys of the 24-square-block area are best explored on foot (parking is difficult). Shops open as early as 9:30 am, closing about 9 pm. Most of the restaurants on the main drag are not very good, so venture off the beaten path for culinary delights. http://www.sanfranciscochinatown.com.
