A perfect way to top of an exotic shopping experience at 99 Ranch.  The Taiwan Express has photos of many (not all) of their dishes. Very authentic.  

Also try some shaved ice for desert (brought me back to Singapore!).  My kids love the shaved ice, though they are more used to Asian foods than most kids.  

Note that the Buffet section (to the left) is better than any mall food courts, and may be more tame for some taste buds.  

AND - in between the buffet and Taiwan Express you can buy a whole roast duck for about $12.50, which they will cut up for you.  Be sure to buy some Plum Sauce (elsewhere in the store) for a sweet dipping sauce for the duck (yummy!).
