So about a year ago my husband and I (gay married) went in with a friend once (long haired guy). We were seated, and first clue we shouldn't have stayed was the restaurant was playing Fox News. The second clue was that when our water glasses were brought out, there were lipstick marks on them and we had to return them all for clean glasses. For some reason, we stayed for the food, and it was, at best, a struggling mediocre plating that one could have picked up at a Piggly Wiggly.
Apparently, the sign is a play on a song by the Signs, but considering the Southern log cabin structure of the building, the Fuax News playing inside, I'm pretty sure this is just the owner's Boomer on display as ample warning to keep anyone from working here.
