About Roadster Diner
Roadster Diner began with a single restaurant in Achrafieh, Beirut, with a simple ambition: to be the homiest, most authentic American-style diner the city had seen. Private booths and pedestal stools at the counter soon filled up, and the brand kept growing: a Beirut delivery centre in 1999, a restaurant in Jal el Dib in 2002, branches in the ABC malls at Dbayeh and Verdun, and a new diner in the mountain town of Brummana in 2017.
Diners across Lebanon, from Beirut and Achrafieh to Jal el Dib, Dbayeh, Verdun and Brummana.
