Roadster diner is one of the most popular diners in Lebanon, and my favorite, and i am not saying that just cause of their really good food. Their customer service is impeccable and believe it or not, this is something very hard to find in Lebanon.
Yesterday, i ordered two sandwiches (Lemon Turkey) and a drink for a friend and myself. 17 minutes later, the order was here, even quicker than a fast food place. However, one of the sandwiches was a Tuna melt not a Lemon Turkey. I called them and reported the error, they apologized and sent 10 minutes later the correct sandwich (Free of charge of course and without taking the wrong one).
Added to that, they called me today to apologize for the error again and thanked me for calling.
