Lattente's original Thames coffee bar sits in Palermo Soho, north-west of central Buenos Aires among the neighbourhood's shops, restaurants, and busy evening streets. The room is compact and direct: order at the counter, wait for your name, use the communal table if there is space, or take a sidewalk seat beneath the trees. This is a coffee stop with a clear rhythm, not a lounge disguised as one.
Lattente's early place in Buenos Aires specialty coffee explains why it belongs in the guide, but history is not the whole case. Thames still gives the brand a focused, coffee-first form: house-roasted espresso, a genuine filter option, bags to take home, and enough pastry for a short pause. The tradeoff is limited seating and a visit that works better focused than sprawling.
Coffee
Espresso is the shortest route into Lattente. Co-founder Daniel Cifuentes represented Argentina at the World Barista Championship, and Thames remains a counter-led room where the coffee reaches the customer without a long all-day-cafe preamble. Start with espresso, cappuccino, or flat white before moving into the wider menu.
The retail shelf is part of the recommendation, not a souvenir rack. Look for a coffee with clear origin detail, ask what is on the grinders, and choose the cup being handled well that day rather than the longest drink description. That combination of bar and retail is why a quick stop can still feel more substantial than a caffeine errand.
Filter
Filter is a genuine second lane, rather than a token menu line added to flatter a specialty label. If there is a coffee with clear origin detail on the shelf, taste it black before deciding whether to take a bag home; it is the order that tests the roastery claim most clearly.
The Thames room is small enough for a short question about the coffee, although the queue will decide whether the visit becomes a conversation or a quick handoff. That is a fair exchange: Lattente is strongest when it gives a precise cup and a reason to keep moving, not when it promises a long, lingering ritual.
Food
Food supports the coffee rather than competing with it. Current menus and posts show croissants, ham-and-cheese breakfast rolls, cookies, budín, granola, and simple morning sets. That is enough for breakfast or a mid-afternoon pause, but not the reason to choose Lattente over Buenos Aires' stronger brunch rooms.
The best order keeps the proportions right: espresso and a croissant for speed, filter with a slice of budín when you have a seat, or a milk drink with one of the sweeter bakes. Treat the food as accompaniment and the room feels coherent.
Service & Room
Thames is built around turnover without feeling anonymous. The counter comes first, communal seating asks strangers to share space, and the sidewalk provides the better perch when Palermo is busy. It is practical for one coffee, a short conversation, or a bag of beans; the compact layout makes a laptop session or long meeting a poor fit even when a chair is free.
The Thames room is the right anchor for this review because the format is easiest to read here: counter first, compact shared seating, coffee on the bar, beans on the shelf. Other Lattente addresses may suit a more convenient route, but this is the one to choose when you want the original's concentrated version of the brand.
Why Filter Notes shortlisted Lattente
Filter Notes shortlisted Lattente because it clears the guide's highest bar: it gives a visitor a coffee reason to choose it over the many pleasant cafes nearby. Cross town for house-roasted espresso, a meaningful filter option, retail beans, and a counter format built around the drink rather than a general-purpose cafe day. Know before going that seating is tight and the food is supporting cast; Thames is a focused coffee visit, and it earns the detour by keeping that promise.
