The chow recommendations (agnolotti with duck, the mushroom polenta, and the bananna tart) were all great. Chowhound got it again!
The 3-course prix fixe lunch is a reasonable $34 (but excluded pasta dishes).
The space is very nice (not dumpy as some have suggested) and the service is terrific.
It's very, very expensive. Eleven agnolotti (which are the size of tortellini) cost $22. They are fantastic (and just enough if it's lunch time AND you are having other courses) but that's a lot to spend for basically a tapas sized portion on a large plate. The terrific polenta dish (a soup bowl of loose polenta and 1/2 cup of mushroom sauce on the side) is $12 but delicious. Bite sized desserts (e.g. the olive oil cake) are ~$10. The other expensive items (soft drinks and coffee) are normally priced ($3-4).
Lunch gets crowded at 1:30. Go at 12:15 if you want an easy reservation. Go at 1:30 if you want company.
