Late night roadfood in upstate NY and VT (between Poughkeepsie and Woodstock, VT)

My traveling partner and i will be driving from Poughkeepsie, NY to Woodstock, VT this weekend, and we can't leave Poughkeepsie until 10 at night, so this will be a late night adventure (not my usual traveling style). I hate to give up a chance to scope out some roadfood. Can anyone recommend any late night/open-all-night diners or such along the way? It looks like we'll be mainly on the Taconic State Parkway in New York and U.S. 7/State rt. 11 in Vermont. We're willing to make some detours or consider other routes, but can't lengthen the trip too much (since we're already getting in at 2 or 3 in the morning :) )
 
Thanks!
