A California classic, In-N-Out Burger makes the rest of the country jealous for their prime cuts of grass-fed cattle, raised uniquely on the West Coast. This fast-food chain is incomparable to its international rivals because of its emphasis on locally cultivated meat and produce. Channeling a retro ‘50s theme to evoke Americana diner culture, the In-N-Out Burger burger joints offer the standard selection of ham and cheeseburgers, fries and milkshakes. However, their ‘secret menu’ offers a few unpublicized options, which you can specify if you want your sandwiches or fries prepared ‘animal style’ (mustard-cooked with extra pickles, cheese, spread and grilled onions), ‘flying dutchman’ (no bread or onions), ‘protein style’ (wrapped in lettuce instead of the carbs-heavy bun), or ‘2x4’ (two beef patties and four slices of cheese). The service is friendlier than most fast food chains, and many locations have drive-thru windows. Best part of all: In-N-Out Burger chains are open late for your late-night cravings.
