his is the only place in the city devoted to the Argentinian street-food favorite known as choripan. Like a supersized version of a grilled Spanish chorizo sausage, it comes sandwiched between two halves of a small French loaf, loaded with toppings and a dollop of tangy chimichurri sauce. The basic no-frills choripan (¥750) is hearty, but it’s worth spending another ¥200 for some lettuce and chopped tomato salsa. Or go the whole hog with the ¥1,100 custom version, loaded up with extra toppings. Apart from the sides of fries and salad, the only other options on the menu are empanadas — tasty fold-over pasties containing either chicken, beef or cheese.
