This is a decent, convenient place for breakfast and lunch. It is in the first floor of the building I work in when I am in Charlotte, which has been almost every week the last 2-3 months. The breakfast is good and made to order- I've had omelets and breakfast biscuits - but it is not fast. Expect to wait 10-15 minutes. I believe you can call ahead and have it ready, but I have not done that. Many times I'll just grab a hot tea, premade fruit cup and a granola bar. The various cashiers are always friendly and helpful.
The only thing I have ever gotten for lunch is the made-to-order salad. You fill out a form with the size of salad you want (side or full), the vegetables/condiments you want (all included - no limit) and then pay extra if you want a protein. It's a good salad and they don't skimp on the protein you choose.
They also have a rewards program - for every 5 visits you get a free coffee.
I wouldn't go out of my way to come here, but for those who work close by it's a good alternative.
