For consistently very good, standard Buffalo wings with the right texture and medium heat, I would have to say Archie Moore's has stood the test of time imo, and they have never disappointed me.
I tend to like mine hotter, and I also like to mix it up with different styles. But most of the other CT places where I've had great wings have not been consistent over time, or from visit to visit. Still, I would include these on the list:
Willimantic Brewery (Oy Vey are my favorites there; Jerk Wings also very good)
Eli Cannon's in Middletown
Bidwell Tavern in Coventry (Dry Mexican Hot)
Porky's Cafe in Shelton
Prime 16 in New Haven (Agave Chipotle)
MiKro in Hamden (whatever confit wings they have are always great)
Rudy's in New Haven (both the Buffalo Lager and Brown Ale BBQ; also serves the best Belgian frites I've had in this country)
