This LA burger chain is a point of pilgrimage for locals and visitors alike. Yes, this is fast food, but In & Out has been hand-crafting burgers since 1948: fresh (not frozen) beef, hand-cut French fries, etc. The basic burger comes piled with lettuce, tomato, secret spread (like Thousand Island dressing) and raw or sautéed onion.
Insider tip: the 'not so secret menu', which you'll find on the website but not on the menu board, features double-, triple- or quadruple-meat burgers; burgers inside a lettuce wrap instead of a bun; or burgers cooked 'animal style' (in mustard). The Hollywood location gets a big after-party night crowd.
