Italian in Cow Hollow?
My two favs in the neighborhood are A16 and Capannina.
A16 does fantastic pizza and starters (I've never been blown away by the main courses there) while Capannina does outstanding pasta.
A16 is probably more of a scene and hard to get a table without a reservation while Capannina is more laid back and you can usually walk in without a long wait.

I second Capaninna. There's also Terzo which originally was small plates but which has added some large plate offerings. They have a wine deal going this summer on Sundays through Thursdays wherein they charge half price for any wine on their list that is $40 or less. Check out their menu first, though, because they may not have the kind of Italian you're looking for.
Pane Viino is on Union near Gough. Haven't been there for awhile so can't really comment positively or negatively.
From Lombard you can walk a block to Chestnut and take the 30 bus to North Beach where there are tons of Italian restaurants (not all of them are good, though).
I've been forced by family to eat at E'Angelo's a few times, most recently a couple of years ago. It's crowded and the food is thoroughly mediocre. I ordered spaghetti carbonara and got overcooked pasta drowned in cream sauce. If you can't get into A16, Emporio Rulli actually has decent pasta, though the service and setting leave something to be desired.
