I am finishing up a weekend in New London, and, it's been a long time (10 years at least?) since I have been here. I can't say that I missed it.
Still, another set of good eats. If you're visiting Groton, stop by the Seahorse restaurant and check it out. Definitely a local feel. Finally, just outside the Providence airport is a local RI chain, Chelo's, who have daily specials that include dessert for $8.99. Complained a little that they didn't have the massive amount of food here for low prices as in Texas, but, that put the lie to that.
Here is last night's dinner at the Seahorse - Scallops over Sole. Pretty tasty.
