I use to go to school in poughkeepsie and went to the hyde park brewery fairly often. I remember them having some good beers. I haven't been there in a few year so I can't speak to how it is now. If you're going to be in the area then it won't hurt to stop by and check it out.
Also, definitely check out the CIA if you can. You should probably call try and get a reservation as soon as possible because they usually book up fast. If you can't get a reservation to one of the main restaurants then you can always stop at their cafe for lunch, which will be cheaper than dinner but just as tasty
