Great choice, good dishes, good wines, decent prices.
Yes indeed as already stated it is difficult on Saturdays to make an advance booking as they only open at 6 pm and only answer the telephone staring at 5.15 pm.
I succeeded in making a reservation by putting a note between their door and door-post. It is astonishing, and rude, that such a restaurant bluntly does not answer a telephone for reservation when closed. And no email either. A veggie Italian going Timbuktu-style anno 2014!
Cons: Timbuktu style communication
