Caffè Latte - Espresso and steamed milk
Caffè Mocha - Espresso, steamed milk and mocha syrup

Basically, Caffè Mocha has chocolate flavored syrup in it.

Speaking of Starbucks and China, I still remember how shocked I was when I came across the Starbucks inside the Forbidded City. Actually, I'm still shocked.
