On a budget? NYC blog Real Cheap Eats, lists a borough-by-borough list of great dishes for $10 or less. And of course the Village Voice best of NY issue contains an extensive food and drink section with reasonable price ranges.
And if you haven't already sussed it out, Brooklyn is where the REALLY GREAT food is. L Magazine focused on its favorite borough for the Brooklyn Restaurant Awards in September of 2011 and the local Brooklyn Paper in November also came up with a list of Brooklyn’s 30 best meals, mainly under $10.
You've got the lists, now go get the grub!
