simbala

This restaurant has been the spot for a few years now - Zagat just slept on this one.  They specialize in Taiwanese dishes, special juice mixes and shaved ice dessert.  Some of the key dishes you should try are the oyster omelette (In Taiwanese: ô-á-chian), Glutinous sticky rice (Zongzi), the Chinese sausages, and duck noodle soup.
Located at a shopping plaza in Arcadia, CA.
Clue: look for a mob of Asians and you'll find the spot.
