Despite the plethora of celebrity chefs and one-of-a-kind restaurants in Las Vegas, the West Coast fast-food chain In-N-Out holds a strange fascination for many people here. This burger joint offers few options, but it has a cult following—and for good reason. You'll only find quality beef, freshly baked buns, hand-cut fries, and milkshakes made with real ice cream. Though the menu is simple, there are some "secret" items (hint: Order your your burger and fries "animal-style"). In-N-Out is open late , and the drive-thru line is almost as long as the line at the counter.
