Wag's was a chain of casual dining (or "family") restaurants owned and operated by Walgreens in the 1970s and 1980s. They were modeled after restaurants like Denny's, Shoney's, and Big Boy in that they were mostly 24 hour establishments specializing in inexpensive fares like hamburgers and breakfasts. The chain was based on smaller restaurants that existed in some of the larger Walgreens stores.
Walgreens sold all freestanding stores to Marriott Corporation in 1988, retaining only a few locations that were situated in malls. By 1991, the chain was completely out of business.
