A small, very attractive storefront has just opened on Ninth Avenue between 51-52 that only sells empanadas, called Mama Empanada (or vica versa). I only sampled a beef and a chicken with a corn shell, but they have a fairly varied menu of different kinds. Overall, not bad. The fillings were not as flavorful as I would have liked, but the corn shell was very good and appropriately crunchy. Two hot sauces were provided and were pretty good.
