I was always told Oscars and went there a couple times. They were nowhere near as good as Addy's in Millard. Addy's is the shit. Eat a couple charbuff by themselves, and you will think they are amazing. Then dip them in their ranch sauce and you will love them on a whole other level. I eat over at The Pheasant on every other Thursday night too. They have very good wings.
Never been there, but I'm going to agree with you simply because of your description. In KC, I suggest Johnny's Tavern and their "Wilson WIngs". They are grilled to perfection, as opposed to the slimy texture you get elsewhere (BW3, etc.). Char-grilled meat is where it's at.
Salty Dog in Council Bluffs has amazing char buff wings. However they are currently being remodeled due to a kitchen fire. I also like the Bourbon BBQ boneless wings at Buffalo Wings and Rings.
Certainly not my absolute favorite, but Costco wings are definitely underrated. What a great price! Get the honey BBQ and then douse them with Sparky's...very good.
Caddyshack is my current favorite place for wings.
1. Home. Deep fry. Bake on wire rack for 30 minutes. Toss with Sparky's.
2. Wings N More in the hood in South Dallas.
3. Pluckers for chain restaurant.
