Very solid place at its price point.
The Cuban stuff is often very good, but not the best and a little pricy for what is cafeteria food in Miami (or at La Unica). The ropa vieja and pork are solid, the steak milanesa excellent, the beans and rice disappointing. Like bad cofee at a diner, hard to forgive, but I will. Nice selection of Spanish/SAmerican wines, mixed drinks and beers, esp. the Dominican beer Presidente.
Coconut rice with shrimp is sweet, gimmicky, but addictive. Tastes a lot like soemthing you might get in Brazil. I'd steer clear of the pricier specials. The Mexican stuff is ok, but I'd focus on the Cuban.
The best part of Cafe 28 is probably atmosphere. Very cool vibe, not overdone. I think that this is the kind of place that San Francisco especially has in spades but other cities have far fewer.
Parking is a train wreck over there with the destruction on Irving. Nearby, check out Biasetti's, Diner Grill, the Long Room, the Ten Cat, Gato Negro (kidding?) Resi's and Snappy's Shrimp House.
