I sadly just found out Buffalo Wild Wings (named for the wings, not the city) last year. It's sad because I think the best chicken wings in Happy Valley are being served out of this little dive bar in Happy Valley. The actual Chicken Wing is standard, large and crispy but where they really stand out is their home made sauce. Apparently the owner has been offered thousands of dollars for the secret recipe (this isn't your typical Frank's and butter) and I can see why.
No ones wings in taste like these, the sauce is sour but sweet and spicy with flecks of either cheese or garlic, I can't put my finger on it. They have great fresh cut fries that are strongly seasoned as well as fish fry, burgers, etc.
They only take cash and wait times for food can get into the hour + range because of their small kitchen, but it is so worth it.
Buffalo Wild Wings will rock your socks off
