Osteria Nino: A Taste of Rome in Burlington, MA
I don't know much about the restaurants in Burlington (although I know you should definitely go to Sichuan Garden / Baldwin Bar in nearby Woburn) but now I can recommend at least one place to eat. Osteria Nino near the Wegman's in Burlington is a solid osteria serving popular items from Rome and beyond.
The breading on the fried calamari is nice and light, they're served with a tangy fra diavolo sauce.
Since it's a Roman osteria, the signature dish is the cacio e pepe - a simple and traditional dish of spaghetti, cracked black pepper, and pecorino romano.
