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.
Daytime café, nighttime bar. Nothing stronger than 30-proof. Delicious beer and really good wine. Kind people run & staff the place. The garden in the Summer is perfect. I make near-daily visits.
