I eat at Subway routinely... ate at Quizno's twice (two different locations), and have no intention of ever returning. I like Subway over Quiznos, Donatos, all of the pizza places I've tried, and all of the local mom and pop shops I've tried. That said, I've been to several Subways that are absolutely horrible, and I'd never go to again (old and otherwise bad bread and veggies, unclean restaurants, charge for extra veggies/meat/dressing/whatever). In my immediate area though, there are several stores owned by the same lady, and they are all great (clean restaurants, fresh bread and veggies, great service, etc).
