Before 1948, car-obsessed Californians who wanted to eat in their autos were served by car hops who brought food out to them.  So when Harry and Esther Snyder opened In-N-Out Burger, the Golden State’s first drive thru, the concept of customers ordering into a two-way speaker box was revolutionary.  The idea stuck and led to a zillion locations.  In-N-Out Burger will even send a cookout trailer to your party or school, and they’re a favorite on movie sets.  The Hollywood rumor mill has it that these burgers are somehow leaner or healthier than average – there’s no evidence for that, but they are definitely fresh meat, cooked to order.  Step inside one of the spotless, retro-styled interiors, and you’ll see whole potatoes being spilt into fries.  A 2 x 2 gets you two patties and two slices of cheese.  But half the fun is the urban legend secret menu that you won’t find posted.  Order the 2×2 “protein” style and it comes wrapped in lettuce sans bun; make it “animal” style and it’s mustard, pickles, and grilled onions instead of raw ones.  Go for 3×3, 6×10, you name it, they’ll make it.  The shakes are made from real ice cream, and don’t forget to request the cool stickers usually just for kids.  One last plus?  In-N-Out Burger is open late.
