Recipe help

There used to be a Richards Restaurant up on Washington Center Rd and it closed down unfortunately. There was a salad with a sauce called the BLT&C salad and came with this amazing sauce. Any former workers or anyone know how to make that sauce ? It was a smokey, creamy, kinda tangy sauce. Somewhat similar to Chick-fil-A sauce but 1000xs better. It's been one of my cravings while pregnant and I absolutely can not stand not having it anymore. I've tried Googling it but to no avail. Please help! <3
