OFF CAMPUS — Tasty is nothing if not an understatement for the burger “Pulp Fiction” catapulted into our pop-culture consciousness. This is a mouth-watering comfort-food man’s burger — a juicy half-pound beef patty, nestled lovingly in a fine-cut-cabbage manger and swaddled in a shroud of flawless ketchup, mustard, mayonnaise, tomato, red onions and Monterey and cheddar cheese, all between a butter-baked bun, light and fluffy fresh with a crust flakey and fragile as the gentle strip of not-wet-not-dry shore at low tide. A Hawaiian kitsch explosion with a worn-in surf bar and continual ’80s-pop CD rotation, Big Kahuna’s in Pacific Beach can’t be missed. The burger and an order of Big Kahuna Balls are the menu’s best, but bring a friend, because this luscious combo of island goodness feeds two. And make sure to wear your best Wayfarers, for you will know you’re in the home of the Lord when you lay this treasure upon your lips.
