I seem to remember a CSI episode that had this very thing. Hah, I found it. The episode is called "Grand Master".

Detailed Synopsis:
"Aiden analyzes Banner's cell phone. She's found a puzzling message in his voicemail, filled with sounds from a DJ table. Danny is working on a cell phone/personal planner, too: he's taken Gayle's sopping wet cell phone and stuck it in a toaster oven. Stella enters the lab to tell Danny that the red paint was nail polish, and it contained blowfish poison. Danny removes the cell phone from the toaster and accesses Gayle's calendar, which has her at dinner at a sushi restaurant, Fuqua Sushi, the night of her death. The pair head to the restaurant, where they see customers eating off naked women, who literally serve as the tables at the restaurant. Danny and Stella question the chef, who tells them he screens the blowfish he serves for poison, so there's no way Gayle could have been poisoned by one of his blowfish. Danny says they need to examine the blowfish."
Watch out for the sushi....
