I think "pearl milk tea"can best represent Taiwanese food. Although milk tea was not invented in Taiwan,only Taiwanese put the pearls into milk tea.At first , most people coul not accept it. Finally,people love to drink it!!
Taiwanese have many table manner. The most important rule is not to put your chopsticke upright in your rice! It's not very polite!!You can leave them flat on the table when you're finished. The other important rule is that Chinese people rarely split the bill at restaurants. Be ready to pay whole thing, or to have them pay for you.
