La Morada on 778 H.Yrigoyen at Piedras and Chacaburo (a few blocks from Intercontinental HoteL) has the best empanadas.
Only open till 3 pm and is packed from 12-2, also only open M-F. Can order to go if too crowded. All are made fresh to order. 12 types. I like Muzz. Tom. Why Albahaca and Jason why Queso the best. For four it cost 36 p. Awesome lunch cheap. Save your money for Poon.
