Here's my review of these, as an American.

McDonald's - bland but fine, good if you want something comfy.
Taco Bell - bad but open late, good if you're hammered.
KFC - terrible how the fuck is this place still in business.
Burger King - better than McDonald's and just as comfy.
Little Caesars - cheap as hell pizza, but used to be a lot better recently it's kinda shit.
Applebees - fine but too expensive for what you're getting.
Wendy’s - best of the "cheap burgers" crowd.
Starbucks - overpriced but comfy, great place to use the wifi if you get kicked out of your house and need to look for a nearby shelter or couch
Dunkins - I will never call Dunkin Doughnuts "Dunkin" that sounds like absolute shite.
ChikFilA - best of the "cheap chicken" crowd, but not quite good enough to be worth waiting an hour in line. known for funding anti-lgbt politicians but frankly every corporation does that.
Outback - fine but too expensive for what you're getting.
Panera Bread - bland and not comfy. maybe comfy for you if you have different childhood experiences than I've had.
Sonic - second rate Wienershnitzel.
IHOP - cheap and good, highly recommended.
Ruby Tuesday - fine but too expensive for what you're getting.
Waffle House - cheap and okay, mildly recommended.
Bojangles - used to be the best of the cheap burger crowd, now mid-tier.
Golden Oak - fine but too expensive for what you're getting.
