Ernie's Liquor on Chula Vista's Third Avenue has stocked craft beer, wine, spirits, and grocery essentials from the same 91911 storefront since 1987. The tequila and mezcal selection anchors the spirits wall, and keg beer is available for advance order — a party-supply format that catering operations such as Baja Tacos & Gourmet Catering draw on when sourcing beverages for South Bay events. A recent interior renovation updated the layout while preserving the neighborhood-store format that has served the Third Avenue corridor for nearly four decades. The beer cooler rotates San Diego County craft labels alongside domestic and imported selections, stocking the same regional brewing output poured on tap at nearby establishments such as Manhattan Bar. SNAP/EBT acceptance on eligible grocery items, Western Union money-transfer service, and a 90-out-of-100 county health score round out a convenience-retail operation built on Third Avenue's walkable commercial grid.
