Captain Bill's, a seafood restaurant set just outside of "downtown" Madison, WI was an excellent discovery. The inside reminds you of an old ship with wood paneled walls, fishing nets, buoys and other nautical paraphernalia. One room features a large central fireplace that creates cozy setting on freezing Wisconsin nights, and there is also a seasonal outdoor patio that provides pretty views of Lake Mendota.
The food is excellent, and reasonably priced for the amount and quality that you're given. I've tried several of their entrees (king crab legs, the steak, shrimp sampler etc) and have never been disappointed. For those not interested in seafood they also offer a variety of chicken and pasta dishes.
If you go you MUST get the clam chowder, crab cakes and coconut shrimp. They're award-winning and featured on the Food Network for a reason!
Go to Captain Bill's. It's excellent.
