Florería Atlántico

front · Speakeasy below Florería Atlántico is better known internationally as a cocktail bar — Tato Giovannoni's basement on Arroyo regularly appears on the World's 50 Best Bars list — but the wine programme beneath the flower-shop façade is one of the most undersold in the city. Sommelier Maite Lavalle runs a list that leans into Patagonian pinot noir from Bodega Chacra and the Bodegas Otronia high-latitude Chubut whites, with a small but serious Loire and Mosel section that gives the bar its only imported edge.

The room is dark, loud, and works best as a wine destination before nine when the cocktail crowd takes over. Ranks second because the wine cellar is genuinely outstanding once you find it, and the Patagonian programme has no real porteño rival.
