The story
Isaac's was founded by two college friends, Phil Wenger and Isaac Williams, who met as students at Eastern Mennonite University in Virginia. The first Isaac's restaurant opened 44 N. Queen Street in downtown Lancaster in 1983. As a tribute to Wenger's father, Chester Wenger, an avid bird watcher and amateur ornithologist, they incorporated a pink flamingo in their logo and named all of the sandwiches after birds such as 'Mallard' and 'Penguin Club' Vegetarian sandwiches are named after flowers.
In March 2017, the company opened their 19th location (an express model), called "Isaac's on the fly" in downtown York, Pennsylvania.
In February 2019, the company moved their headquarters from Lancaster to Camp Hill, citing lower rent costs.
