This choripan is an Argentine sausage sandwich built on grilled chorizo, bread, and chimichurri, with the kitchen presenting it as a core steakhouse staple. The version here fits Balvanera’s South American grill style, so the sausage-forward filling is the point rather than a heavily dressed sandwich. Expect a smoky, savory bite with a crisped roll that soaks up the herbaceous sauce without losing all its structure. The restaurant’s menu and local listings both identify choripan as part of the dining room’s Argentine lineup.
