Does anyone know what this sauce is called? Buttery/VILLAGE INN restraunt

Question

They used to served it with the portabella chicken skillet at Village Inn restraunt. It looks buttery. I am not sure how to descibe the taste. My mom loved that dish but they discontinued it a year or so ago. Her birthday is coming and I thought it would be a nice suprise to make it for her but I don't know what the sauce was called to research a recipe. Thanks to anyone who helps. I know that my describtion doesnt help much.

Answer 1

Could it be a Hollandaise Sauce? Just a guess, I don't even where your particular Village Inn is. I think there might be one in every city across the U.S. Or even if you are in the U.S.?
