I love buffalo wings, but my problem with restaurant wings is that they're just not hot enough. Sure, they work fine for most people, but I like my wings with a lot of kick.
That's why I like Buffalo Wild Wings. They have a wide array of sauces that you can choose from that differ in flavour and intensity, from a mild honey barbeque or teriyaki to the extremely hot Blazin' sauce, which is hot enough to give me, someone very tolerant of hot sauces, the sweats.
Its a restaurant built around buffalo wings, so the menu isn't very varied; if you don't want wings, there's a few other dishes you can choose from, most containing chicken in some form. The food is tasty, but not exactly as cheap as one might expect from such a place such as this.
At least at the location in Champaign, the cigarette smoke is pretty overwhelming, and its pretty much impossible to go in and come out without smelling of smoke yourself.
The environment, other than that, is good. There's interactive trivia that can be played, large screen TVs that show sports games, a bar... it's a good hang-out place with good food.
