I finally visited Cav this weekend, and I LOVED it. I've been curious about it for a while; I'll definitely go back, very soon. Anyway, I just wanted to let Chowhounds know that they had some wonderful truffle dishes on the menu. The truffled mushroom crostini was divine, but there's also a sample of three available (which includes a frittata and raviolini). I don't know how long this is or isn't on the menu, but it shouldn't be missed.
