Bardaixa
Bar · Sant AntoniVermouth bar/bodega with tapas and tostadas, LGBTQ-run (Travel Gay: 'LGBTQ-owned and run tapas bar and winery', 'friendly gay staff'). Terrace and an interior with an old mural, plus a bright back room for small events; good wine and beer selection (including IPA on tap), dog-friendly, wheelchair accessible. Not a lesbian or party spot as such, but a daytime and evening place (vermouth, cañas, tapas). Opening hours conflict: chateemos.com/a search snippet say closed on Tuesday, weekdays 9:30–23:00, Fri until 01:00, Sat 10:00–01:00, Sun 10:00–22:00; comproalbarri.com instead says Mon/Wed/Thu 10–24, Tue 17–24, Fri 10–01, Sat 11–01, Sun 11–24. Status 'unclear' because no dated evidence from recent months was found (but no sign of closure either); Instagram @bardaixa exists, content could not be loaded.
Assessment: queer-friendly 3 because it is LGBTQ-run with queer staff (Travel Gay); according to reviews (Tripadvisor, chateemos) the crowd is a mixed neighbourhood crowd in Sant Antoni, hence 'locals' and 'straight-friendly mix'. Solo 2: a tapas bar with a terrace, fine for a vermouth on your own, but meeting people isn't the point. Group 3: tapas to share, terrace, event room at the back. Price level 1–2 according to reviews ('excellent value'), 1 assumed here. The name 'bardaixa' is an old Catalan slur for gay men, apparently reclaimed here (assessment, not confirmed by the owners).
