If you've not been to a Waffle House before... well... that's pretty odd, but this is a good one to start at. Basically, they have delicious breakfast foods, and then a variety of other lunch/dinner options, but if you're at Waffle House and you're not eating breakfast, you're doing it wrong.
It's a diner, so the atmosphere is great. Sit up at the bar and watch them prep the food and enjoy the delicious smells, or grab a booth by the window and stare out into the parking lot while you try to ignore your hangover.
The people working here are friendly, and the establishment is clean. The food is prepared well, and delicious. I recommend the biscuits and gravy.
