Dinner in midtown next week (within walking distance of either Rockefeller or Flatiron)

I am seeking any non-particular recommendations for dinner next week (Tues-Thurs) within walking distance of Rockefeller Center and/or the Flatiron District. Only restriction is no restaurants that require a dress code (and obviously I need to be able to access them by next week without any reservations or on short notice). Does not have to be a restaurant either (can be takeout, mall, food court, food truck, etc.). Any price range
