This younger sister of Perbacco (next door) stretches its lanky, lean interior with original brick walls, a long marble bar, shiny stainless steel, and contemporary photos evoking a dizzying sense of motion. Barbacco's style is matched only by its efficiency, and FiDi regulars appreciate that the staff is equipped with hand-held POS systems to keep them on the go. Busy at all times, Barbacco serves impeccable trattoria fare as well as takeout bites. Braised chicken thighs with Castelvetrano olives, garlic confit, and escarole; or squid stuffed with spicy pan grattato and rucola make for heart-warming meals. And, as at Perbacco, the rustic, homemade pastas are perfection—imagine canneroni coated in a slow-roasted lamb sugo with peas, mint, and chili.
