I live and work in Brooklyn, and love it. However, every Monday and Wednesday night, I make the trek after work to my night class at 59th Street and Lexington Ave in Manhattan. When I get out of class around 7PM, I'm ravenous! Any suggestions on good, moderately priced food in that area? I'm looking for something between $10 and $15. Also, I change for the Q train at Union Square, so recommendations around there would also work. Thanks in advance!
