Great cafe right outside of my office (City Square). It's always busy, but the lines move quickly and they manage to get your food out in a reasonable amount of time. The owners (husband and wife duo) are always there working the counter or in the back and are extremely pleasant.
With regards to the food, you get pretty large portions and the quality is always good. I once had a chopped salad there (on special) and it rivaled some of the fancier restaurants I've been to. I tend to get the salad with tuna and for $6.50, it's more than sufficient for lunch. The drinks are very cheap as well...right around $1.25 for a huge cup! My coworkers hit the cafe up every morning for coffee and usually for lunch since there aren't very many options in the area.
Most of the items on the menu are $7.00 or less, which is a great price for lunch downtown. They have everything from breakfast sandwiches, to pancakes and french toast, to burgers, to wraps, to salads. You name it, they've pretty much got it. If you need a quick spot to grab lunch and you're in the immediate area, definitely stop in.
