Late dining near the Marina?
I cannot think of any pizza-place type places that would fit your bill. Mamacita (modern-mexican) might work but you'd have to reserve well in advance.
Laiola is phenominal and kitchen is open until at least 11, I think 11:30 and the place doesn't close down until midnight or later on Saturdays. Might be hard to get 10 people sitting together, though.
Actually, I think Amici's is open until 11 if all you want is pizza and a place to sit.
I agree with the poster who said the best pizza in the Marina / Cow Hollow is at Orgasmica, but there is no place to sit there.
There are quire a few places open late in the Marina with no television or loud music, but which tend to be full and have open kitchen so loud anyway: Laiola, A16, Mamacita are open until 11 pm on Saturdays. By 10 pm should not have a problem getting a table for 10 at A16 or Laiola.
