Inside the gorgeous Park Hyatt-Palacio Duhau is one of the city's finest wine bars, under the eyes of Marcelo Rebolé, a local celebrity sommelier (yes, such a thing exists in BA!), and his young team. It's a beautiful setting to taste Argentina's best wines, whether seated by the fireplace or in the palatial garden on warm days. There's also an impressive Cheese Room, with the best local artisanal cheeses to pair with your vino tinto. Start your evening off here with a Malbec from Mendoza, Pinot Noir from Patagonia, or a crisp Torrentes from Salta.
