My colleagues and I are terribly bored of the handful of sandwich joints we frequent for our lunch and need some new inspiration around 59th and Lexington. We love the meat cart at 62nd and Madison, but sometimes the lines are so long- and we don't have a lunch hour. I also like the empanada guy on Lex and 53rd. Anyone know any good, hidden spots that serve up interesting food real fast for $5-$7? Save us from Subway!
