After walking the Chinatown in Philly, I was amzed to see TWO Taiwanese restaurants next to eachother. I don't think we even have ONE here in SF. Out of curiosity I went into the one that claimed to have authentic Hsingchu type rice noodle.
I ordered the advertised rice noodle and the fish ball soup. The flavours were spot on. Puts SF to shame in a hurry.
