I think we've discussed this at some length before when the DR came up. Can't find it. Here's my take, as someone who has travelled around the DR several times, who knows a bunch of folks who have lived in the DR (in towns and cities, not resorts) and who has had Dominican neighbors -- great people, great country, great baseball, great cigars and rum, unremarkable food, both as a cuisine and as a place to eat, and even compared to other places in the Caribbean; indeed, even among the cuisines of
Hispanola. I LOVE the DR. The food just isn't that great.
There's little that is purely Dominican that can't be found at a Puerto Rican or Cuban place. Chicharones de Pollo, sancocho, mondongo and mangu all have analogues that I think are the same as or objectively better from other Caribbean countries. Certainly, the bland mangu is bested by fufu and especially mofongo. Not that I wouldn't welcome a good Dominican place or 2, but the already underappreciated Puerto Rican places should scratch whatever itch one has for this food.
Habibi and I share an affinity for Presidente bien fria, and I wish they'd bring that back to the Chicago market. Dominican places come and go in Humboldt Park/Logan Square. The legendary RST was interested in the cuisine and would report, as would I. It's been a while since I've paid close attention. My DR connections haven't mentioned any new places recently.
