Chain Restaurants Burger Mini-Meme!

Sooner or later, we all end up at a fast food counter, ordering a burger(or a combo!) off a large, unchanging plastic lit up menu hanging above a group of workers that would rather be somewhere else! Today's challenge is an easy one:
1. What is your favorite fast food place to eat, and what do you usually get..
2. What is your least favorite fast food chain, and why...
No snobs saying "I've never been in one"- I've seen every race, color, and creed in these joints!
As is my tradition, I will go first...
1. Favorite? Culvers. Relatively new to West Michigan, their burgers aren't the cheapest, but are my favorite (Double Cheeseburger, everything but onions, please..).
2. Least Favorite? Checkers. Or Hot n Now, or Get'em n Go. These are drive thrus that have taken up the bottom of the fast food chain... Uber cheap- and fast! However, the food is barely edible and I have not felt well later that same afternoon. I have tried all of these- once! The only one with doors still open in this town anymore is Checkers- the other two bagged it, and I'm glad they did!
Your choices may be only be in your part of the world, but if they have more than 20 outlets nationally, they qualify today!
