We'd heard of In-N-Out from our friends who lived out west for years, but living on the East Coast, we'd never had the opportunity to visit, until our trip to San Fran. Founded in 1948 and styled as a retro-style diner, this burger joint is well worth the visit, especially for a cheap meal in an expensive city.The menu is shockingly simple, with only five items (hamburger, cheeseburger, double hamburger, fries, drinks/shakes) ranging from $.99 to a couple dollars. Fresh ingredients is what this place prides itself on; no burger is ever frozen, and the potato is cut on-site when fries are ordered. Of course, being vegetarians, my husband and I thought we'd be out of luck for the main dish, but there is a "secret menu" that the regulars know. We ordered a "grilled cheese: animal style", and it was amazing! "Animal style" is code for "all the toppings please", which include lettuce, tomato, mustard, pickles, grilled onions, and extra special sauce. You never would've known our burger was missing the meat! So, if you're ever in San Fran, make a stop at the famous In-N-Out - well worth it!
