I didn't develop a point-based scoring system, but following your posts made me wish I had. I just have an overall descriptive rating. Likewise, no formal categories, but I think about things like size, quality of chips, quality of cheese, variety of toppings, and distribution of toppings. My findings so far have been that even mediocre nachos are still nachos, so no major disappointments this far.

So far our favorite has been El Buffalo in Canton. Looking forward to trying more nachos.
