How about listing some Fast Food restaurants that went out of business ... that had a unique taste to their food. Some of the ones I remember ... Burger Chef ... as I recall ... the burgers didn't taste like McD or Burger King. I think they became Hardees but that did not taste like the Chef ... as I recall. Red Barn ... as I recall they had unique tasting chicken ... not like Kentucky Fried or Famous Recipe. You can still see some of their old buildings around ... look like the picture below.
