For a really nice meal:
1) Pez Dorado on Sol St by Altagracia Church (very large portions, food is famous here)
2) Montmart (?) on Calle 2 in the Jardines, in back of Politecnico Femenino, off Texas av.
3) ZOL on 11 St, off of Metropolitana, just by Bon in the Jardines. 11 is a One way St,
4) Pasticcio had received good reviews, also.
5) Nano's, on Benito Juarez in Villa Olga, left side after the ball park-known for its meat
6) La Parrillita, on Juan Pablo Duarte, across from Plaza Internacional.
I have not mentioned Carlos Tasso because last time I went by there it was being renovated.
For me either 1,2 or 3 are most impressive for a date.
