Love Manna Cafe! They are friendly, the atmosphere is awesome and the coffee rocks. Love that it is local. The food is really good. The salad dressing is very good. I like that it is kid friendly, too. Mr. Square Head is a very cute peanut butter sandwich--and they serve puppy chow as a side to kids meals!
I'd give it 5 stars, but it is a wee bit pricey, like many other places in Madison. $7 for a tuna sandwich and side (small) salad.
