On Casimira de Moira.. between Pasteur and Cervantes.. a little place formerlly called Louis Phillippe.. now called TIpico Dominicano.. best small place for lunch..very crowded at peak lunch but if you wait too long they will run out of chicken liver.. their pasta with chicken or fish is better than places for twice the price
Across the street from there is a Dominican place that serves the most excellent desserts...! AYEEEE the chocolate cakes.
Also Ananda which is vegetarian and has a sort of garden cafeteria .. live music, I have heard, on Fridays..
Also right opposite La Cadena.. outdoors.. the diner -- line up ... decent Dominican .. outside.. get a table in the shade and sit.. also go after the noon rush.. best place to meet the locals. Lawyers and such from the Court on the corner stop for lunch.
The cafeterias both at Clinic Abreu and Centro Gynocologo are very clean, air conditioned, fast, cheap and decent.
Not to forget Hermanos Villar on the corner of Pasteur and Independencia.. where you can simply spend the day .. full service from breakfast to lunch, to dinner. sit all afternoon in air conditioning.. watching the folks go by... bakery in the back.. or eat in the garden BEST coffee in the Hood..
More upscale is right across the park behind Clinic Abreu.. opposite the Boyscouts.. in a Hotel.. tableclothes. amazing food-- must be Swiss? because they have fondue and rosti but make a wonderful shishikabab of chicken....
The Nabu restuarant in Hotel Crowne Plaza is excellent.. they have the MOST amazing lambchops. Great service.. all around excellence
I have not been to the Sheraton since they closed their pool to the public.. I assume they have a restaurant.. The Hilton's food is mediocre..
There is excellent Charrasco at a little place called Charlie's .. it has a wooden front.. on the side street off the Malecon..one down from the Centro Cultural.
And my all time favorite..is Cappucino's which is on the edge of Gazcue.. across from the Texaco station. Amazing home made pasta..home made ice creams.. great dishes.. reasonable prices.. great service. never disappoints..
And there are others.. but .. that should be enough for a month.
