This is one of my fiancee's and my favorite places in Madison. The only downside is that you have to pay cash. All the food we've gotten is great. I love the chili and cheese omelet, my fiancee loves the scramblers, and the pancakes are great. Also, you have to try the coffee shake with chocolate syrup added - seriously to die for.
The other thing to consider is the seating - if you come during the "peak" hours, expect a wait and be ready to pounce on any open seats. I like to come right about 1 - most people have cleared out by then.
