I'm looking for a place to go with a group of 8-12 people for my birthday (so preferably that takes reservations) with decent decor, that isn't too expensive, for a Saturday lunch in a few weeks. Union Square would be preferable, but anywhere (not uptown, not too hard to get to) that is fun to walk around for a few hours is okay too. It'd be a bit of a reunion, so somewhere where it's not too difficult to linger would be preferable. We're all teenagers so alcohol prices and such are not an issue.
It doesn't need to be vegetarian, but it has to have at least one decent vegetarian option (I am a vegetarian.)
edit: A place where lingering is okay and we can have our own big table reserved would be great.. :)
