I guarantee you that nothing like Volt existed thirty years ago. We had a group at the lab where I worked that went out to lunch every Wednesday, trying different restaurants. Not that the selection was huge. Mr. Nutrax was living in Wash. DC at the time, so we also explored places in nearby towns.
A lot of "cuisine" was still influenced by the fact that the original settlers were German, plus there was a later influx of Pennsylvania Dutch. It was very common for dinner to be preceded by an appetizer that consisted of a trio of bowls filled with cottage cheese, apple butter, and three bean salad.
There was a Vietnamese refugee family who had been resettled there and given a grant to open, of all things, a Mexican restaurant. They did a pretty good job. There was a crummy Chinese place (we took a high school student intern there once--he was from a small MD town and had never eaten Chinese food, not even canned chow mein. He ordered fried chicken.) A lot of Southern fried stuff. (I had never thought of MD as a Southern state.)
And don't get me started on the quality produce, or, rather, lack thereof.
