A nice chill atmosphere with everything that's needed in one place. Great neighborhood with an abundance of options for both groceries/eating in and going out. Two of my favorites nearby are El 58 (per Guillermo's excellent suggestion!) and El Abasto. Give them both a try - wonderful food and very friendly folks. Only suggestion perhaps is if you're on foot, I highly recommend renting a bicycle or bringing your own. Truly easy to get around and see more of the city up close/personal.
