This area is easily explored in half a day. The best time to visit is morning, when the popos (grandmas) shop—it's cool out, and you can enjoy a cheap dim-sum breakfast. Chinatown is a seven-days-a-week operation. Sundays are especially busy with families sharing dim sum in raucous dining hall–size restaurants.
If you're here between January 20 and February 20, check local newspapers for Chinese New Year activities. Bakeries stock special sweets, stores and homes sprout bright-red scrolls, and lion dancers cavort through the streets feeding on li-see (money envelopes). The Narcissus Queen is chosen, and an evening street fair draws crowds.
