SIFÓN Sodería is a great spot if you want to try local food but can't take any more steak. The menu features traditional items like oxtail empanadas and chard fritters. These are the things that abuelas make and it's food for the (Argentine) soul.
The cocktail menu features, you guessed it, soda water. The Sifon is a staple in Argentine culture so order up a vermouth with soda to drink like a local.
Also, SIFON opens early, which is ideal for those who haven't adjusted to the late Argentine dinners. They open at 6 pm during the week and are open all day on the weekends.
