This place opened up recently and I finally stopped by for a quick snack.
Located on Washington Street in Hoboken, this small cafe makes all kinds of Argentinian empanadas fresh daily. They also serve strong coffee which is always a plus.
The chorizo empanada was delicious. For $3 an empanada, it's definitely better than grabbing a hot dog from a street cart in the city, or overpriced bar food. They do catering and online orders as well.
