Piccolo Cafe, Gramercy Park, Manhattan
I am often on the search for coffee. Particularly a cafe latte. I've been to a few Piccolo Cafes in the city and I've always had a good one. They also have some Italian food which is quite good. Their locations that I'm familiar with are very cute and quite small. On their website they say they've been in business since 1938. I'm not certain where their original location is. They have 4 locations in the city and they are based here in the city. They also have an app now as well which I haven't tried.
Piccolo Cafe, 157 Third Avenue between 15th & 16th Streets
