For anyone driving through CT on 95... Mystic: Sea View Snack Bar.
This place is on the side of the road about a mile off the mystic exit, and has just picnic tables outside facing the bay. It's a cute little place, with awesome new england style seafood... scallop rolls, lobster rolls, fish and chips etc. It's pretty cheap, and one of my favorite places I've been on the east coast. Definitely worth stopping if you're driving through.
