I Shop Liquor on Fourth Avenue in downtown San Diego's Gaslamp Quarter is a veteran-owned liquor store pairing a walk-in retail floor with a Shopify-based e-commerce storefront offering nationwide delivery. The shelf selection emphasizes hard-to-find tequilas and small-batch spirits that supply the same Gaslamp craft cocktail corridor anchored by The Tipsy Crow on Fifth Avenue. Operating since 2021 under California ABC off-sale licensing, the Shopify-based storefront extends the Gaslamp inventory to direct-to-consumer buyers with nationwide delivery on spirits, wine, and beer subject to state-by-state shipping regulations. Inventory rotates through bourbon, rum, gin, cognac, vodka, and cordials, with particular depth in rare and limited-edition tequila releases from highland and lowland Jalisco distilleries. The curated bottle selection targets pre-dinner and post-dinner purchases for visitors dining along Fifth Avenue, where Fogo de Chão Brazilian Steakhouse anchors a high-spend block. The store specializes in single-barrel añejo and extra añejo expressions requiring estate-specific agave sourcing and extended American or French oak barrel aging programs.
