Wingstreet used to have the wings called Flamethrower were banned after a while because they were too hot... or at least that's what I heard. I couldn't eat more than 3... you needed something to drink after eating just 2 or 3.. it was insane.
Wild Wing Cafe in Katy has really good wings with a ton of flavors. The lunch time wing buffet is awesome
I love me some wings. I stopped going to wingstop ever since I tried the wings at Bayou City wings and pizza off of Kirby and 610. The wings are big and the flavors are good. Try the spicey creole, lemon pepper and parmesan garlic. Much better than wingstops. Also Cabo has some good wings and so does Niko Niko even though they don't specialize in it. The new Fiery Grilled wings from KFC are actually pretty good though but I can't eat more than 10 because it becomes a bit bland. The Bayou City wings that I'm talking about is not associated with the other Bayou City wings though.
