What, no prick in here being holier-than-thou by saying they don't eat fast food at all? I'm proud, NG.
Of all of my fast food adventures, McDonald's still takes the cake for best fries. They're consistently the best, especially when fresh. My only complaint is that they usually put too much salt on them. Arby's has damn good food, but it's a bit expensive. If I just want a sandwich, I get a plain Ham-Lettuce-Shredded Cheese on Wheat at Subway.
I actually haven't been able to eat much Taco Bell after getting the flu and barfing up a meal of it about a year ago. Trust me, having any food come up will ruin your taste for it. It kind of sucks, I loved Taco Bell, the Doritos tacos are awesome.
I'm not a big fan of Wendy's, have only had a few meals there lately that I enjoyed.
