Do yourself a favor and go to Great Harvest Bread Co!
I love this little place. There's nothing better than freshly baked bread and this is the place to get it. The staff here are so sweet.
My favorite bread is The Dakota. Sunflower and pumpkin seeds make this loaf amazing.
The sandwiches here are yum. They only have 3 vegetarian options, that's my only complaint. I'm a fan of "The Masters": pimento cheese, spicy pecans, hot pepper jelly, lettuce, cucumber. Mmmm.
You're going to pay a little more than you would at the grocery store obviously, but the quality and simplicity of the ingredients make it worth the cash for me. FYI they have a coupon in the Charlotte Citipass book: buy any loaf and get a honey whole wheat loaf free!
