Sorry, I knew I'd forgotten that important point! If you go down to the east side of the drawbridge in downtown Mystic, the same side as the big flagpole. Facing the drawbridge, to your left, the last street before one can goover the drawbridge, is Cottrell (I think). Anyway, turn left down that street, so you are headed south towards the water. The Mystic River with the boats, etc. will be on your right. John's is only about two or three buldings down on the left or east side. There was a seashell shop across from him and a photo developing shop next to him. I will look it up tonight and find out the address for sure, but you can see the old sailing ships from his place up river,so it's not far from the Seaport.
