If you are in Madison and you need breakfast/brunch, you need to immediately seek out Horst's.
Their biscuits and gravy are my lifeblood. I devour a plateful every time I'm there. The staff is quirky and friendly, just like the decor. You can't beat the prices either! Sometimes, you have to wait for a table, which can be awkward because there simply isn't enough room inside to do so. Most times, the staff will let you wait outside and come and get you when a table is ready - keeps you out of their way :)
Also, whatever you get to eat, please get a glazed donut on the side for your table to share. This is the most important part of this review. You'll thank me later.
