One of the best places to eat at in Madison. Great vibe inside, beautiful. It has a nice view of the lake. The seating outside on the deck is great as well. Get reservations.
Oysters are always on point. Highlights are the Sardine Burger (get it with gruyere & cheddar), moules & frites, Steak Frites, Seared Salmon.
I always make a point of stopping into Sardine when I'm back in town for business.
