I'm pretty sure that's real. "VIP Sample" along with a return address and phone number on a sewn-in tag, and anyway "BURBERRY PRORSUM" is spelled correctly here. Presumably this was something they kept for showing to their baller VIP by appointment customers.
I don't usually dine in expensive restaurants that have Peking duck on the menu. The fish was awesome, but didn't think to take a photo. Most of the other meat dishes I've posted are Mongolian, like cleaved sheep skull and vertebrae.
