Mellow Mushroom Pizza will bring back selections from its original 1974 menu on August 20th in a “Way Back Wednesday” celebration to mark the brand’s 40th anniversary.

For this one day the chain’s three Orlando area locations will be offering a small cheese pizza for $2.50, drafts of Michelob/Budweiser/PBR for 75 cents, and Coke products for 30 cents.

Customers will also have a chance to win a trip to Amsterdam for two. Pose in-store with a backdrop of the first Mellow Mushroom location and post it to Instagram with #40YearsBaked to enter. Those without an Instagram account can upload their images to 40yearsbaked.com.

Mellow Mushroom is located at 2015 Aloma Ave in Winter Park; 11680 E. Colonial Dr in Orlando; and 18221 US Hwy 441 in Mount Dora. For more information, visit mellowmushroom.com.
