I have not, myself, been there, but San Francisco has the Pirate Supply Store.

826 Valencia is a non-profit organization in the Mission District of San Francisco, California, United States, dedicated to helping children and young adults develop writing skills and to helping teachers inspire their students to write.

826 Valencia runs San Francisco’s “only independent pirate supply store”. The store is the front entrance of the tutoring center and has the look and feel of an authentic pirate shop.[5] It sells pirate clothing, eyepatches, compasses, spyglasses, pirate dice, skull flags, and secret treasures. It features handmade signs, scattered around the store, offering tongue-in-cheek wisdom, such as “Uses for Lard” (#5: “Lard Fights”) and “Guidelines for New Shipmates” (#4: “No forgetting to swab”). Unsuspecting visitors are sometimes treated to surprise “moppings.”

Shoppers can also find back issues of McSweeney’s Quarterly Concern, books published by McSweeney’s, and literary compilations written by 826 Valencia students. The books of student writing published by 826 Valencia include forewords, illustrations and interviews from public figures such as Former San Francisco mayor Gavin Newsom and actor Robin Williams.

The Pirate Supply Store was originally created through necessity. After being turned down for regular use of church basements and school facilities, the founders discovered an empty store on Valencia Street. City ordinances required businesses in that area of the city to be either retail or catering, so the Pirate Supply Store was opened in 2002 as the “legitimate” business front for the writing center. It also helps fund the tutoring program.[6]
