My Family and I spend every summer in cavendish and every year we make an effort to eat at the sandbox. The Food is always great. except for one time, but they got us a new order and comped it off the bill. So i can't complain!
Also there was an actual sandbox there! So when my wife and two boys went, my wife and i could sit in peace while our two boys were playing in the sandbox.
I also enjoyed going there at night for a few drinks.
