Since the 1950s, Langer's Deli has been serving the best pastrami in LA. Some say the best in the world. Regardless, between the famous #19 sandwich and their menu of Jewish classics like blintzes and kugel, this place isn't going anywhere.

Owned and operated since 1922 by the Lawry's family of seasoned salt fame, this Scottish hunting lodge-themed restaurant was a favorite haunt of Walt Disney's, and has been unchanged since. He probably ordered the prime rib, and you should too.

Philippe's opened in 1908 and they've been serving French dip sandwiches for almost as long. Regardless of whether they invented it, they make a mean one. Pro-tips: decide what you want long before you get in line, and try the spicy mustard.

One of LA's classiest old-school gems, and the only 24-hour steakhouse in town, this elegant spot has been open since 1921. Housed in a replica train car, they're famous for nonjudgmental service, a time-warp setting, and consistently great food.

Musso's, as the regulars call it, is a bar, a restaurant, and a Hollywood icon. When they're closed, someone is filming here. When they're open, you might spy a celebrity. Frank Sinatra ate steaks and got drunk here. We won't tell if you do too.

This beloved burger joint looks retro now, but that's because it's barely changed in the 70 years it's been open. With renowned burgers and house-made pies, the Apple Pan has truly earned its motto of "Quality Forever."

Pie 'n Burger is the undisputed king of the Pasadena burger game. There's a reason why: they're consistent. From the waitresses (one has worked there since 1963) to the menu, it's the same as it ever was. Grab some pie and a burger, and give thanks.
