Roadster diner is a Lebanese restaurant chain inspired by casual American diners.

The restaurant has a 1950s–1960s American diner theme ^[1] accompanied by various memorabilia of the time.

It was founded in 1998 with the opening of its first branch in Achrafieh and now has ten dine-in branches and four delivery centers.

Roadster diner is an ISO 22000-certified company since 2004.

In 2003 Roadster diner company also founded another restaurant chain, Deek Duke, which also carries a casual dining theme but has chicken as the main menu item.

Initially the restaurant's menu contained traditional American diner staples, but with the years new items were added to the menu to accommodate for local tastes in burgers, as well as adding Mexican food items, such as quesadillas and fajitas, and other international menu items such as pastas.

Additionally over the years the casual dining theme has also grown to accommodate for family style dining.

As traditional American diner menus containing burgers, sandwiches, milkshakes, fries and other calorie packed items are considered unhealthy and receive a lot of criticism, in 2011 Roadster diner added a new low-calorie menu which contains 7 burgers and sandwiches offered with a side salad, all of which are less than 500 calories, to accommodate for healthier options.

Their new menu has recently been praised after adding specialty platters and sandwiches in addition to curly fries.
