Gotta be Micky D's! First of all I love their fries (since there's no Burger King around here anymore - their fries were the best), second we only have McDonald's and KFC around here for chain ff places and I absolutely loathe poultry in all forms. And lastly, once upon a time many years ago I worked for an ad agency that handled all McD's advertising for 3 states. So we got BOGO and free item coupons all the time. Can you guess what we all had for lunch every day?
Yes, you can get very full for $3 at McD's ... I'm an adult, order happy meals and find them very filling.
Taco Bell ... shudder. I ate at one of those years ago, what a mistake. Lard in everything, saltiest food I ever ate and just gross tasting. That stuff is not even close to decent (let alone good) mexican.
Wendy's, tried a few times when there was one near me, something about the fact that they stew the burgers before frying them just is kinda eh.
There was another place, White Castle, that had a rep for great burgers. I wouldn't eat them, they had ground liver in 'em
I don't know some of the places you all go to, funny how certain places are regional or limited to certain countries. McD's is everywhere -- that's the only constant I know of.
