My mom and aunt asked me to write into the Forum for them as neither of them have access to a computer.
They told me the ice cream at Dewey's was fantastic - and they should know as they are both 80 yrs old. (Unfortunately they told me about this find after I left for home from vacation.)
Mom said she had a maple walnut ice cream and it was filled with nuts and the ice cream was very creamy. My aunt had the chocolate ice cream sundae and she said there were chucks of chocolate in that and they thoroughly enjoyed it. If they weren't leaving to come back to NY the next day I'm sure they would have gone again.
Not sure when they will close for the season, but the owner tell them they would be open for some time in October
