You need to make a reservation for L'Artusi years in advance... or at least the week before, if you try a walk-in then ask to be seated at the bar, as always in New York that is the best seats at any of my favorites restaurants.
This quaint shop boasts an artfully arranged and tastefully curated selection of jewelry, pottery, books and art. I have to keep myself from going there too often, because I have trouble leaving without making a purchase.
