As a point of reference, I really miss the Mushroom Ravioli from Bistro 110 in Chicago. The kind that I constantly crave is one that is smothered in creamy brown mushroom sauce. Their menu description is "wild mushroom-filled ravioli in a sauce full of morel mushrooms and port wine." The sauce comes out brown and I am sure that it is filled with butter, sage, and lamb stock. I can't explain why I crave this, but it's just so rich and delicious!
The only mushroom ravioli in Manhattan that's come close is the one at Il Mulino, but it's not as thick most likely because they don't have the stock.
I would like to find something that doesn't require a reservation, homemade. Any casual bistro or old school Italian suggestions? Most restaurants have mushroom ravioli in tomato sauce or something else, but it's the sauce that I crave most!
