Two diners I had never been to, Luna Grill and Diner in Shirlington and the Arlington Diner in the Shopping Center at S. Glebe and Arlington Ridge Rd. have much in common. Prices are reasonable to low, food is nothing special. They also both have another thing in common. Although the prices are about what you'd expect, you still feel a bit cheated after you see the total bill in relation to what you ate.
It's easier to dislike the food at Arlington Diner. Augelomeno soup is served extra gloppy and just about room temperature. Just what I want on a cold wintry day. Burger is about the same price as Ray's Hellburger and only three thousand times worse. A gray, dense disk of flavorlessness.
Luna Diner in Shirlington has hip decor,at least. But the turkey dinner I got seemed out of a can.
Trying to eat out cheap? Look elsewhere.
