Emeril Lagasse samples some celebrated San Francisco treats as he visits the City By the Bay. His trip takes him to the Buena Vista Cafe, the eatery that introduced Irish Coffee to America, and learns to mix the classic drink. He discovers a wide variety of fresh seafood from cracked crab to calamari salad at the Swan Oyster Depot, where generations of Sicilian recipes reign supreme. And he ends his cook's tour by visiting the longest-running restaurant in California -- Tadich Grill. There, he samples a unique California creation, The Hangtown Fry, so named because this tasty frittata was the favored "last meal" by convicts awaiting the hangman's noose.
