PimpinDG, the first time was at a Fuddruckers I was as impressed as you were. The burgers were done very nicely, just the right way, the topping looked good and tasted good and the atmosphere was quite pleasent.
Since then I have been at different locations many times and my summary would be: Inconsistent. Often I was disappointed with the location being uncomfortable or not very clean or the burgers tasting all that great, etc. But then once in a while I go back again, and I'm pleasantly surprised.
Overall the concept behind Fuddruckers is a good idea, they just need to get the place to consistently live up to higher standards.
