Each Great Dane location consistently has the worst service in Madison. On a recent trip, we waited 45 minutes for a table (which is typical, so we didn't mind) but then once we were seated, the waiter didn't come over and great us for nearly 20 minutes. This is after we had asked the hostess if we even had a waiter. On a different occasion, our appetizer was forgotten. The slowest service ever as well.
They're lucky their food is so good and beer excellent. But don't come hungry because you will be waiting for awhile.
