Delgadillo's Snow Cap Drive-In, Route 66 drive-in restaurant in Seligman, Arizona, United States.

Delgadillo's Snow Cap Drive-In is a low, single-story drive-in on Route 66 in Seligman, Arizona, built in 1953 by Juan Delgadillo from scrap lumber from the Santa Fe Railway yard. A deep orange awning runs along the front below a white sign band reading "SNOW CAP" in blue letters with painted mountain peaks; a yellow plaque sits on the roof's left and a cartoon ice-cream cone on the right. The counter band reads "MALTS", "Creamy Root Beer" and "SHAKES", and the serving wall is covered with murals, menus and painted ice-cream cones. A tall red-and-white pole sign reads "BURGERS" and is topped by a shield reading "DELGADILLO'S", "66" and "SNOW CAP".

Juan Delgadillo built the Snow Cap Drive-In in 1953 on a very small budget, using scrap lumber from the nearby Santa Fe Railway yard. He added a roofless 1936 Chevrolet hardtop decorated with horns, emblems and an artificial Christmas tree to draw travelers on Route 66. The restaurant is a contributing property in the Seligman Commercial Historic District.

The place takes its name from the owner's family and is known for its playful style, where visitors from around the world have left business cards covering the interior walls. This collection shows how the restaurant has drawn people from everywhere.

The restaurant sits at the east end of Seligman and is easily reached from Interstate 40 exits 121 and 123. It opens daily from 10 AM to 6 PM, giving travelers a clear window for a quick meal stop.

The counter door has two knobs, one on each side; the right one is a dummy and only the left one opens it. Juan Delgadillo also asked customers whether they wanted cheese on their cheeseburgers and listed "dead chicken" on the menu.
