Garlic Herbed Fries are a variation on the chain's Bottomless Steak Fries that tosses them in a garlic herb seasoning and finishes it all off with shredded Parmesan and parsley.
As an added treat, this Friday on Halloween, Red Robin will offer a $3 discount when guest upgrade to Garlic Herbed Fries, a "monster" burger, or "monster" milkshake at participating locations. A "monster" burger is one with an extra patty (normally it's $1 to $2 extra, varying with location). A "monster" milkshake is shake with a refill tin that's usually $1 to $2 more. Basically, the Halloween discount covers an upgrade or two.
According to the fine print, the deal is only good on 10/31 from 11 am to 5 pm off a guest purchase of $10 or more.
