After 92 years in business, Formosa Cafe on Santa Monica Boulevard quietly closed in January. The restaurant joins a long list of shuttered Hollywood institutions like Chasen’s and Don the Beachcomber. In his new book, “LA’s Legendary Restaurants: Celebrating the Famous Places Where Hollywood Ate, Drank and Played,” George Geary pays homage to the spots Tinseltown’s elite once frequented. He also shares recipes for classic dishes like The Brown Derby’s cobb salad and the C.C. Brown’s 1909 brownie sundae.
