A Poble-sec corner bar near Carrer Blai — vermut, cañas, a few plats, neighbourhood pace.
Bar Olimpia is one of the small corner bars in the streets immediately south of Carrer Blai, the Poble-sec pintxos street that fills every weekend with visitors counting toothpicks. Olimpia is what Blai used to be: a single small room with a tiled bar, a vermut barrel, a chalkboard of three or four plats, cañas poured for the neighbourhood. Eater's Barcelona neighbourhood guide groups Olimpia with the "Carrer Blai survivors" — the bars that have not pivoted to the toothpick economy. Time Out Barcelona's Poble-sec coverage flags it as "the alternative if Blai feels too much".
The right visitor wants a vermut and a short plate of patatas bravas before the Mercado de la Boqueria walk, or a 22:00 wind-down caña after a Carrer Blai pintxos crawl that has already gone on too long. The wrong visitor wants tourist-friendly service, a long cocktail list, or a kitchen open past 23:30. Olimpia stays in its neighbourhood-bar lane.
The room is small and uncomplicated: a marble-topped bar along one wall, a few high tables, a small back room with maybe four tables, and a chalkboard of three or four plats that rotates with what the kitchen has. The decor leans functional — tiled walls, a hanging cured ham, family photos behind the till. The Infatuation Barcelona's Poble-sec coverage describes the layout as "the Carrer Blai bar before Carrer Blai became Carrer Blai".
Order the house vermut (around €2.50–3) or a caña; the wine list is short and Catalan, by the glass for €3.50–4.50. There is no cocktail menu, and the bar staff will tell you to walk to Bobby Gin or Two Schmucks if you want one — honest advice the bar runs on.
Food is the chalkboard: patatas bravas, a daily plat (often a slow-cooked meat with chickpeas), a tortilla, a few cured-meat plates. Regulars on r/Barcelona consistently steer toward whatever the daily plat is; the static tapas list is fine but not the reason to come. The kitchen winds down at 22:30 — later eaters get sent to the Carrer Blai pintxos line.
Most of the room is Poble-sec resident — older couples at lunch, neighbourhood after-work groups, a Catalan-Spanish bilingual feel at the bar. From around 21:00 the crowd skews younger as Carrer Blai overflows; the bar will sometimes be the alternative for a group who has given up on the toothpick queue. Time Out Barcelona's neighbourhood writer calls the room "the Poble-sec corner bar template".
