Tom Gates, Matador Nights
Arguably the best Japanese food in Buenos Aires is at Comedor Nikkai, which is, not surprisingly, located in the Japanese Cultural Center (Av. Independencia 732, San Telmo).
The spinach appetizer still makes me drool while daydreaming. Sushi plates are fresh and generous. The chirashi is among the best I’ve ever had, and I’ve housed a lot of raw fish. Great sake and a very friendly staff. Rivals the best sushi I’ve had in New York or Japan.
