Dorrego Square! This plaza is like seeing everything…read moreArgentinian all at once. This place is amazing! I went by here on a weekend, when they were holding the weekend antique market. This small square packs in the action. There was a dance troupe doing tango demonstrations. Their loudspeakers drew in the crowd, and they put on a thirty minute show that involved all the histories of tango dance. Around the plaza, they had antique stalls set up, selling seltzer bottles, signs painted up in the Argentinian lettering style, old records, pins, lamps, sculptures, lots of pictures of Evita. Around the exterior of the square, there are cool restaurants, bars, and antique shops. Most of the bars focus on tango and accordion music. When I went, there was an accordion player in the street, playing Yankee Doodle on the accordion when I walked by... This scenic bar is right in the heart of San Telmo, which is a really neat old neighborhood with scenic buildings, and the whole art fair on the weekend.
