Downtown Yonkers Lunch?
If you ever make it back to Yonkers, here's the wikipedia page for Getty Square so you can get your bearings.
I'd highly recommend walking around Van Der Donck Park, where the Saw Mill River was "daylighted" after being under a parking lot for a century. The beautiful signs tell the whole story, and the history of the area.
Just a quick off-topic bit of info that may get deleted (sorry, mods):
We had an awful time trying to get my son's passport (his childhood one expired and he needed to get a new one for a trip next month) through our local post office in Scarsdale. However, dealing with the County Clerk's office in White Plains was so quick and painless, we were shocked. There was no wait and the clerk we dealt with, Julie, was incredibly thorough and unbelievably friendly. If you encounter any kind of wait in Yonkers, I recommend White Plains. We visited on Friday, January 3 and (using an expediter) got the passport back Friday the 10th.
