My book group is looking to explore Manhattan and / or the boroughs, so we're looking for diner or brunch places that can seat ~ 6, fairly quiet (it is a discussion group), with good food and coffee. One of us is vegan so it can't be all meat. We're willing to do boroughs as long as the place is near a subway. We meet Sundays at 2 pm so it's after the main rush but we also don't want to feel rushed as we sometimes hang for 2 hours. Budget-wise, we're hoping for <$15, none of us are big drinkers so the +bloody marys or mimosas inclusive meals won't be necessary. Thanks in advance.
