I don't know why other people have such problems with decent fast food, but locally all our fast food is IMO decent, if not great. I've argued with people online about how bad McDonald's is, for example, ours is just fine localy.
But them I'm in northern Michigan where we laugh at healthy food, heh.10 years ago when I lived in Boulder Colorado, there was one Burger King, one McDonald's, and one Pizza Hut, and I believe there was on KFC. The three years I lived there, the Pizza Hut closed dwn and a fruit smoothie place opned in it's stead. Locally, in a city one third the size of Boulder, we have just in the city limits three McDonald's, thee Burger Kings, two Taco Bells, one KFC, two Pizza Huts, and this doesn't include the other half dozen misc same stores withing a mile or two of the small city limts.
Anyway, I like Arby's. Don't eath there much as they're kind of expensive. Same reason I don't eat much at KFC. Arby's is the last holdout, at least locally, that has NO budget menu, let alone a 'dollar' menu of some kind. KFC just started theirs, though nothing is a dollar, at least they have a budget menu now.
Until Arby's comes up with and advertises heavily a decent, value oriented dollar style menu, they'll keep sliding downhill. The main Arby's here in town, it's been here at least 30 years, it's almost a landmark. And, the food is fine. Go for the curly fries next time.
