If you want another destination, bring your dinghy or small boat to the guest dock at CYC, north of the clubhouse. Walk over the foot bridge and there are two popular restaurants. "The Tavern at Croton Landing" and the "Ocean House".
The tavern is a pub/grill place with nice food. The pizza is very good as are the wings and salads...heck everything I've had there is good. 
Ocean House is a great seafood place but small so it's tough to get a table, no reservations. You can check in / put your name on a list then go next door to the tavern and wait. Ocean house has no liquor license so bring your own wine.
Anyone can tie up at CYC guest docks.  You don't HAVE to check in with anyone as we don't have a harbor master or even a bartender on staff.  If you want to be polite, check to see if anyone is in the club house and if so, let them know your intentions...we appreciate stuff like that.  Or what I would do is leave a note on my boat with cell phone number just in case.  Also, if possible, do not use the side of the dock used by those launching and retrieving boats.
When at restaurant, please mention you used the docks at CYC, one owner is a member, the other is very familiar with us.
Unfortunately, our liquor license says CYC is a private club for members and guests only so we are not officially open to the public but be my guest.
