OK - a real long shot. I hope someone can help.
A couple of years ago, a friend and I stumbled upon a really solid Mexican food place on the way back from the Eastern Shore. We were so hungry and it appeared out of the blue - I don't remember it being in a "town".
Definitely closer to the Bay Bridge than the shore. We have not been able to find it since. I don't remember which road we were on. It was stand-alone and in a long narrow building? Maybe a gravel parking lot?
Probably a hopeless quest, but thought I'd see if anyone out there knew what I was talking about.
