I was able to check out Don Frito a Puerto Rican trailer on Beacham St across from the New England Produce Center -- "fritos y comida criolla". While some of the outside signage is somewhat temporary, the inside is much nicer than it was as a Salvadoran taco stop (it was a middle eastern restaurant in between which I didn't get to check out). It looks like its been open all summer. They have about 6 tables, a laptop playing bachata at moderate volumes. There is a daily rotation of meat specials (4 listed per-day, but didn't seem to have that many ready) and appeared to have some substitutions. For $7.75-$8.50 you get meat, rice, beans and I believe a small salad.
Some interesting things. They offer a tripleta on the sandwich menu and also apparently have cuajito on the Wednesday menu (again, they definitely weren't to the letter for daily specials when I visited) which I would like to try. As I mentioned on the openings thread, they offer lechon assado on Saturdays.
The list of fried items is reasonably long and now having seen it, I should have asked if you can order a la carte because they only had 5 items in the case. emparrillada de carne, pollo, papa rellena, alcapurria de yuca, and one more fried emparrillada.
Overall I expected more from the food and it was greasy, but I did really like their seasonings. The emparrillada de carne was the better "frito" and they might make their own dough (or at least its not the goya masa para empanadas fritas). The alcapurria was tasty, but a bit greasier. Chicharron de cerdo was a bit overdone and they heat it to order, but the skin was crispy and not tough. Chicharron de pollo had good seasoning, but fried a bit too much and not enough skin. The cerdo wasn't quite as good as some Dominican and Columbian places, but better than Bella Isla. Izzy's de pollo was more preferable. I did enjoy a fried chicken leg, which came with quite a lot of breading. Yellow rice had habichuelas and not gandules -- decent, less greasy than Cafe Latino, but I prefer Izzys with the gandules and more onion. They had roast chicken in the warming case and I didn't see the pernil, but its offered all days and I was there on the early side. There were one or two things which might be made to order on certain days like "bistec encebollado"
Since Bella Isla involves less potholes and avoids delays turning onto 99, it'll still be my first choice. And while I can forgive some greasyness, there was a bit too much overcooking for my likes. However, there are a few things which are going to draw me back, the lechon, tripleta, cuajito, and other fried items, as well as the pernil.
