Having been to the original many, many years ago, the differences are price and ambiance. The ambiance is better than the stark nature of fast food places in the 70s. They also deliver your food to you at booths and tables. The burger is more expensive than the other low cost chains. Prices are comparable to Five Guys. I did have the Gino Giant with the special sauce.
I thought the burger was good not great and would probably give Five Guys the nod. My two favorite burger chains are In n Out and Shake Shack to give a comparison.
But I do appreciate the old management team for buying the brand back and Gino himself was in attendance at the opening of another Gino's in Maryland this fall.
