The Old Fashioned is perhaps the best fish fry in Dane County. The cod is flaky and fresh without the grease or fish smell. Even the fries were somehow really good.
The bar is giant and the service is decent. I can't speak to the rest of their menu, but the Friday fish fry is worth the wait and worthy of the acclaim. Better still, the prices are terrific for downtown Madison and the portions are huge (two people could easily split the $10 Friday cod). Unfortunately this place is no secret and they don't take reservations so be prepared to wait.
