I've recently had char kway teow at Penang Garden in SF Chinatown and Banana Island in Daly City. Both versions were made with dried wide rice noodles, maybe double the width of those used in pad thai, rather than fresh wide rice noodles, like those used in pad kee mao and chow fun.
Anyplace in SF or elsewhere in the Bay Area that makes char kway teow with fresh wide rice noodles?
