I work near City Hall in Manhattan and I'm looking for good lunch places as far north as Chambers Street (roughly) and as far south as the Staten Island Ferry. I would prefer cheap places where my co-workers and I can go for a casual, cheap meal that won't take too long. I don't mean places for business lunches. We're a gregarious group that loves to eat but our challenge to each other is to try to find places where each person spends no more than $10, although we're willing to compromise for the best tacos, falafel, Cuban sandwiches, pho, or whatever other "best" is out there. Let's hear your suggestions!
