Quivey's Grove is definitely a nice Wisconsin experience. Their pretzel battered fish fry is phenomenal. Really everything else was ok, but the fish fry is the reason I would go back again.
The restaurant is adorable and is in a rustic stone house. Or you can eat at the stable. Either way, you're in for a treat. I've heard that they host some fantastic wine tastings. I may look into that for a future get together or birthday with friends.
I feel like this is a less well-know restaurant, at least for the average Madison diner. That said, it's crowded on Friday nights...plan ahead.
