More food for fewer dollars: 10 best budget-friendly Las Vegas restaurants
"In-N-Out is a burger place that hasn't strayed far from its roots as a basic drive-thru hamburger restaurant. The succinct menu is all about the burgers--you won't find chicken sandwiches or salads at In-N-Out. You also won't see the "secret" menu that In-N-Out devotees find so exciting: options like "protein style," with the patty wrapped in lettuce, or the most popular choice, "animal style," with pickles, extra spread, and grilled onions."
