Having lived in the SF Bay Area for 24 yrs before moving out here almost 2 yrs ago, the only real cheesesteak I know is from this Bay Area chain.

They are hella good though, and they have chicken ones too that I'd affectionately refer to as a 'Chickencheese'. 😅

Many years ago, they also had the best burgers ever. The burger meat got too expensive so they discontinued them. They were so addictive though. 😭

I did have the occasional one at Charleys but that was in the mall food court and seemed more like an average sandwich versus real cheesesteak so I didn't count those. 😬🤷
