I'm biased because I eat there more than twice a week, but for a fast meal that is very friendly on the wallet, I recommend you check it out.
Fat Jacks has a great breakfast that beats the competition on any day. 3 eggs. Grits, home-fries, or hash-browns. Toast or biscuit. For around $2.50.
For lunch try the Sloppy Jack, but have them add cooked green peppers and onions.
