Our Take on BASA Bar

Microcentro is a neighbourhood built for daytime: banks, law firms, corporate offices stacked twenty floors up on streets that empty after 7pm. BASA is the exception. Descend the stairs on Reconquista at 6:30pm on a Thursday and you find 24 seats occupied by the kind of people who prefer to end a working day with a precisely made drink rather than a bottle of wine at a mediocre restaurant down the street.

The bar runs a monthly rotating menu of 10 cocktails, each paired with a two-line description and a price that reflects Microcentro overheads rather than Palermo markups. The bartenders trained under some of the city's best programmes and bring that rigour to what could easily be a forgettable basement room. The technique here is excellent: proper dilution, accurate balance, and no creative noise for its own sake.

The room itself is low-lit, narrow, and entirely functional. There is nothing about the decor worth photographing, which is why everyone in it is talking rather than looking at their phones. That alone makes BASA one of the most enjoyable after-work bars in Buenos Aires. Pair an early session here with dinner nearby, or continue into the evening at 878 Bar in Palermo if you want to keep drinking at the same level.

What to Order

Monthly Signature
Whatever leads the menu this month. BASA rotates its entire card on the first Monday of every month. The lead cocktail is always built around one Argentine producer or ingredient.
The BASA Sour
The one constant on the menu: Argentine pisco, lemon, egg white, aromatic bitters. Made correctly every time, which in the after-work category is rarer than it sounds.
Old Fashioned (House)
Single barrel bourbon sourced from a Tucumán producer, raw sugar syrup, four dashes Angostura, hand-expressed orange peel. A reliable benchmark for the skill of whoever is behind the bar.
Fernet Highball
Not on the menu but always available: Fernet-Branca, ginger beer, lime. The bartenders mix one for themselves between service. It is the correct drink at 6pm in this building.
