Arvi Is Via Quadronno between Madison and Fifth - it's very narrow, with a bar on your left as you enter, with a seating area at the back, with excellent sandwiches, mostly on a ham/cheese theme? If so, I concur in your view that it's a great espresso bar. One of the nice things about New York is that it can blend the American service culture with the best that Europe has to offer, so it can in a way be better than the European original. There is a French cafe on Lexington called Payard, that is similar, with wonderful chocolates. Lunch at Aureole looks like a steal. La Goulue is good for people watching. You might want to try Le Bilbouquet as well. There is also a restaurant on Lexinton called Orsay, which is good. I have heard it called Div-Orsay, because of the large number of blonde upper East side divorcees who lunch there.
