My all-time FAVORITE fast-food joint is a small, Michigan-based chain called Hot n Now. Drive-through only, they're called Hot n Now because they make sure you get your food fast, with very little wait time. And their burgers are HEAVENLY.
They get the buns crispy on the edges, and make sure to put lots of condiments on. (Too many times i've gotten an burger from other fast-food joints with only a drop of ketchup & mustard on it..)
Sadly, they filed for bankruptcy a few years back. The last time I had a Hot n Now burger was in 2007 or 2008 I believe. It's a Checker's now.
Their Chicken sandwiches, were, hands-down, the best in all of fast food, easily beating Burger King and McDonald's Chicken Sandwiches.
And Cheese Teasers.. ohhhh. I didn't try those until shortly before they closed down, but they were DELICIOUS. Like a mini hash brown stuffed with cheddar cheese.
I know it's silly of me to say this, but I am genuinely depressed over it. Hot n Now was a huge part of my childhood. I've eaten their burgers from ages 8-23. and I've yet to eat a burger from any other fast-food joint that's as good as theirs. The idea that I'll never eat another Hot n Now burger for the rest of my life makes me want to cry.
I guess my second pick would be Burger King.
