Expect sweet and savory Italian indulgences, ranging from torta, tiramisu and other pastries to an array of tasty small plates, at this reasonably priced cafe that Ristobar’s Gary Rulli opened atop Union Square; order a proprietary-blend espresso or authentic Italian hot chocolate and watch all the hustle and bustle from the glass-enclosed patio or one of several outdoor tables.
