Ah, good memories of Mighty.... the Bailey/Minnesota location was the bomb. And I was a VERY frequent guest at the Walkden & Union location...
They've definitely changed things up since 40 years ago. That said, the wife and I were in the Buff for a family wedding a few weeks ago, and we stopped at MT for a quick lunch. They were better than the last few times I had visited in the 10+ years since I moved away. Big, saucy, no skimping on cheese. Close to the "old days."
Wings at Duff's were bangin' too!
