I, too, am fond of La Masseria. West Bank Cafe is also a respectable standby.
Many (most, I'd venture) restaurants in close proximity to theatre serve until 11 or midnight. You shouldn't have any trouble finding a place. If you find a place that you like, check their website or call and ask how late their kitchen is open.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
