I lived near a Duff's. The conversation over wings is no different than the coffee places. Timmy's vs. Starbucks. Timmy's coffee, to me, is flat out bad. Although not as bad as McDonald's or your average convenience mart. Why people will leave for work early to sit in a long-ass line for that stuff, I'll never understand.
Same is true when Duff's comes up. Living near Duff's I had on several occasions received the most nasty order of wings possible. The first time I got sick. The following times I was able identify they were bad and took them back. After a few times I have never been back.
Meanwhile, Anchor, to me, has always made their wings right. Always. Big wings, perfectly cooked, sauced correctly. Every time I see people crap on Anchor,. I simply don't understand how it's possible. I prefer Anchor over the other, high-profile locals. La Hacienda Brighton also makes a mean batch of wings.
