California. In a nutshell Produce, citrus, walnuts, strawberries, lemons, avocados, raisins, seafood, etc. Mexican, Asian, fusion, healthy lifestyle cuisine, organic. Exception is the In and out Burger. No popular fried foods except fish tacos. Gourmet(?) creative untraditional pizza from chef Wolfgang puck, i.e. smoked salmon, cream cheese & caviar pizza, pizza with an egg in top. Avocado toast. Dates (date shakes) from Indio California. Danish pastry and pancakes (aebelskivers) from Solvang. Wine from Nappa Valley in Northern ca. Fresh Strawberry stuffed donuts became popular from a small donut shop/store. Driving up the coast, when you roll down the car windows you can smell the oranges in the orange groves. Still thinking.
Eta: Farmers' markets are popular here. Farmers sell their locally grown fresh fruits and vegetables, seafood and wares/shops. One of the oldest and best, imo, is the Hollywood Farmers market in Los Angeles. There are several restaurants there as well, that serve tasty meals at a good price. Pink's hot dogs has been around for quite a while. Great dogs, with a wide variety of choices for toppings.
Olvera street is popular for it's Mexican food and wares.
Philippe's in downtown Los Angeles is famous for it's French Dip sandwiches.
Canter's in Los Angeles known for Jewish food/deli, and my faves potato knish & the black and white cookie.
As you drive up the coast, further away from Los Angeles, you can see cows (dairy and beef?), and rows and rows of crops. Lettuce perhaps.
