"Open since 1937, the Jim Dandy Drive-In is a Portland institution and one of Oregon’s oldest drive-ins. The menu is so extensive, it is not published online, and this includes their milkshake menu with more than 100 flavor combinations. The Sticky Fingers milkshake — a mixture of vanilla, peanut butter, and Butterfingers — is usually in high demand."
