Okay, okay. I've posted my first and last negative note to the list. Now for a contribution:
Yely's Coffee Shop on Center St in Jamaica Plain, towards to Roxbury End, across the street from the Jackson SQ Orange line station. It's a Dominican take-out place, and I don't even think they serve coffee. What they do have is a big case filled with Dominican delights: chicharron (not just the skin, but with the fat and pork left on, seasoned and deep fried), chuletas (pork chops), chicken (roasted or fried), boiled yuca with red onions, maduros (ripe plantains), tostones (fried green plantains), etc., etc. Try the Dominican spaghetti. Lots of stuffed fried things with local names. Big fat slices of fried salami, long skinny fried beef sausages. They'll fill a big styrofoam box for you, and eyeball it for a price -- usually between five and seven bucks. Instead of coffee, get one of the bottled neon drinks. Bring your chowhound Spanish, or at least an index finger, and you'll get what you want -- with slices of lime on the side for squirting over everything! Stand eating at the small counter, then find a big rock to crawl under; you'll need a three hour nap to recover.
