The only place you can eat (according to locals) on the water is Down the Hatch with its expansive outdoor seating and high decks offering a peaceful view of the lake (Candlewood Lake).
They have a couple of lower outdoor sections as well and the place appears to be very popular during the season.
I had the full lobster dinner ($19.95) and was surprised how tender and juicy it was. My wife took on the Caribbean sandwich ($8.95) which was very tasty as I stole pieces from her plate.
Service was good (although it was not a busy day) so for our part the experience was good.
Note to Management: cleaning up the unused tables and the floor on a more regular basis would enhance one's experience.
Definitely would go back there next time we're in the area!
