It's cozy, and they've got tunes.
The first time I set foot inside the trailer of La Piraña (the nickname of the proprietor, though he appears as even-tempered as you would hope of anyone whose principal tool, used in the normal course of chopping lechon, is a machete), I was only up for snacks. An exceptional golden crab pastelillo (also shown in biteaway view) was not long out of the deep fryer; I chased it with a darker ground-beef-and-green-plantain alcapurria.
A platter of the roast pork called lechon ($8) is exceptional, too, provided you give the nod to several ladles of gravy on top. Cheek by jowl with rice and pigeon peas are tomato, onion, celery, and mysterious additional tidbits of flavorful protein — perhaps smoked meat, perhaps bacon, one dining buddy conjectured.
Note that the trailer itself is not labeled Lechonera La Piraña. Look for the Puerto Rican-themed mural on one side (Aguadilla is the proprietor's previous home) and the "Pan, Tierra, Libertad" logo on the other. Note, too, that quarters are very close inside. If the weather is brutal, consider waiting to pay a call during the annual, amiable Festival de la Calle 152.
