Cathy Erway, author of “Foods of Taiwan,” hits a Chinatown market and then makes the island’s most famous dish, beef noodle soup. At Taiwan Bear House, started by homesick young expats, Danielle tries a New York take on the box lunches known as biandang. And in California’s Orange County, she pays a twilight visit to America’s closest counterpart to a classic Taiwanese night market.
