Best wings in the Twin Cities can be found at the Wing Joint in Blaine.
It's my opinion wings should stand on their own without sauce......sauce on the side is acceptable. I treat wings just like a dry rub rib. I've been going here for over 20 years.
Q Fanatic in Champlin has some fantastic smoked wings (as well as unbelievable ribs, chicken, and brisket) and some spectacular homemade bbq sauces. My favorite is the espresso bbq. It sounds prissy, and I normally HATE bbq sauce, but once you taste it you know whoever made it knows what they are doing. Order ahead.
