"...and the Gamberi Fra Diavolo tastes like bird droppings"

I was looking at an online menu for a little Italian restaurant in Whitefish, Montana called Mambo Italiano, and something struck me as odd. Next to a few items on the menu is a little symbol that looks like a red sprig of something. At the top of the page, I read that the sprig represents Mambo Recommendations.

So I'm wondering, if Mambo makes every item on the menu, why do they only recommend a few? Do they not care about the other dishes? What happens when a customer asks about the Sun Dried Tomato Penne, or the Linguini Alla Carbonara? "Oh no, sir, we don't recommend that one at all, it's disgusting."
