There are about 14 restaurants within walking distance of my house.
For sandwiches: La Campagna: They have four locales: One is on the road to Gurabo, just past Hache going towards Puerto Plata on your right. Another is on Duarte Ave, just past Plaza Internacional, on your right, Another is on Calle6 in Los Jardines in back of the Politecnico Feminino and the fourth is on Jacinto Dumit, off of Bartolom? Colon.
For good food, any style: PeZ Dorado (across the street from La Altagracia Church --the big white one with twin towers you can see from the Monumento--one of the oldest and best in Santiago. Wear a sweater!)
Also for fine food there is ZOL on Calle 11 just around the corner from Bon on Av. Metropolitana in the Jardines.
Also on Calle 2 in Los Jardines is a wonderful place run by Juan Torrens and his wife. Left side about 2/3s of the way down the street.
The is Pasticcio in back of Nacional Supermarket, good Italian.
There is D'Amici on Calle 11 in Los Jardines, across the street from La Epoca
I also give votes to la Parrillita and to Nano's on Benito Juarez in Villa Olga, just past the baseball field.
