This is the link to their web site. However menus are not updted
The 9 course menu costs Euro 195 or Euro 170 if you choose 6 courses from the same menu.
Make the reservation well in advance and remember that you will need a 15-20 minutes car ride to get up there from Rome City center.
I wish you all the best!!
I know it's not exactly what you were asking, and it was a few years ago, but I thought would pass this along anyway. I dont think the prices have changed much and this thread might provide some use to you even though we didnt do the tasting menu.
