Humboldt 1542, Palermo
LAB is about as hipster as they come in Buenos Aires, a hyper-contemporary space aptly named given they treat the roasting and brewing process much like a precise science. A café for the true coffee connoisseur, every accouterment is available here from Chemex and V60, to an Aeropress for the perfect custom brew. Décor-wise, the space is a mix of white walls and blonde wood with low-hanging modern lamps and plenty of natural light. Aside from the incredible coffee, we recommend the grilled cheese or a sweet-savory slice of banana bread if you're feeling peckish.
Av. Del Libertador 1902, Palermo
In a city that has a picturesque café on every corner, Croque Madame has the distinguishing factor of being part of the very beautiful Museo Nacional de Bellas Artes. The outdoor terrace is a buzzy, cozy situation surrounded by lush greenery, the ideal spot for a continental breakfast (flaky croissants, OJ, endless jam), or a quick coffee. While admittedly there are a few Croque Madame Café’s dotted around the city, this one is all about the location—surrounded by museums, it's perfect for a caffeine-centric pick-me-up between exhibits (with some stellar people-watching on the side).
