For burgers you can't beat 5 Guys. Grilled onions, grilled mushrooms, jalapeƱos, and steak suace makes a damn fine burger.
For pizza I like Papa Johns. Dominos, Pizza Hut, and Pizza Inn are all still pretty good. But pizza is a lot like sex. Bad pizza is still pretty damn good.
When I find one I can't pass up a Chipotle. Those burritos are amazing. That cilantro rice they put on there is fan-freakin-tastic. It is great. We have a Blue Coast Burrito around here, but ts just not the same.
As for the bad, well I can find something I can eat just about everywhere. I even like McDonalds. It doesn't really qualify as a burger. It's its own little animal, literally.
