There's Pat's Country Kitchen in Old Saybrook, which is a neat place to chow down after chasing sunrise stripers on the CT coast.
Then there's the Spurwink Restaurnant in Cape Elizabeth / Scarborough Maine....great food before or after fishing.
And finally there's a great little place in Pulaski that I've hit the past few years after spending the day chasing pike on Lake Ontario. I can't remember the name, but it has great pastas, sandwiches, and the like all available for sit-down eating. Cleats allowed for river anglers, too.
