Burger King Goes King-Size With “Big Dip” Cups Of Hidden Valley Ranch: Burger King and Hidden Valley Ranch are teaming up to give “Big Dip” energy. The food brands collaborated to bring fans a wide, 8-ounce cup of Hidden Valley Ranch, perfect for dipping Whoppers into and a large upgrade from the usual one-ounce sauce containers at BK. But the best part of these? The price, because they’re free when you buy any Burger King sandwich. Unfortunately, the Big Dip cups are only available in select BK locations in New York City, Los Angeles, Chicago, Miami, Dallas, Houston and San Francisco starting October 16th. But fans in other areas can still try to snag one for $1 on hiddenvalley.com starting at 10M Today (October 16th) and they’ll restock them every day at that time through Friday (October 18th).
