If there is, how would you rank them and why?
For the life of me, I've never been able to discern a difference.
But while waiting in line at the market today, two ladies in front me were having a rather heated discussion about the merits of Carrows versus Bakers Square versus Denny's. For a minute there, I almost thought that they were going to go to blows to settle the issue. (One of them did pick up one of those rubberized separators and started waiving it rather menacingly, however.)
I'm not asking if these places are any good (that's a separate issue).
I just want to know if there is a real difference between any of these joints?
