The Chowhound Team split this discussion of California food code from the Los Angeles board. If you'd like to comment on the food at Din Tai Fung, please redirect to this original discussion:
From my understanding, it is due to health standard in U.S. DTF in Taipei obtains fresh (Unfrozen) pork daily, and they are allow to use the traditional bamboo steamer basket. In U.S. it would be difficult to obtain unfrozen pork, and also the health standard does not allow DTF in Arcadia or any restaruant to use bamboo steamer basket to serve customers. Next time note what the steamer basket is made of. Of couse the unfrozen pork versus frozen pork meat will impact the taste far more than bamboo versus stainless steel steamer basket.
