If you have the American Express Platinum card, use their free concierge services. They had people calling and writing in italian to get us into everywhere we wanted to go. Rivetti (La Spinetta) was the hardest and they didn't confirm until after we left and had no email access to know we had an appointment.
Eat some angnolotti with tartufo for me!
If you are looking for a thin crust pizza (NY/NJ style), find the Todds shoe store (near the Cinima in the old town) and across the alley is a lttle pizzeria that had carafes of local village barbera, barbersco, barolo.... Splurge on the truffle pizza and you will be amazed! Sit outdoors if possible.
Just make sure there isn't a busload of Germans there in front of you at Marchesi or your tour reservation for 2 means nothing...

After that experience, I'd add instead Vietti, Rocche dei Manzoni, Scavino, Conterno Fantino and Prunotto.
Enjoy!
