Anything in Mantoloking?
I'm pretty sure the Mantoloking YC is on the other side of the Bay.
Frankly, that strip of the Island is a chow wasteland. To me, the only 'hound-worthy spot remotely nearby is Mueller's bakery in Bay Head. Back in the day, Central Market, also in Bay Head, made subs that were decent enough to take for a day fishing. Last time I was there, though, the place was pretty dank.
