Nestled in the nexus of quirk that is Clinton Street—its neighbors include Scandinavian cafe Broder, the velvet painting-adorned dive bar Dots and, of course, the Clinton Street Theater, famous for its weekly screenings of The Rocky Horror Picture Show—Sub Rosa seems downright quaint, with its small dining area and classy decor. It keeps things simple, offering artisan pizzas and pastas with unfussy accoutrements. About as weird as the place gets is the Northwest by SE pizza ($18), which comes with carmelized onions and pears as toppings. Otherwise, it’s just high-quality Italian served with genuine smiles. Its tagline is “a friendly neighborhood joint,” and that’s an apt description.
