Awesome food. Went here with some friends from Baltimore that got some crab legs and they said it was delicious. I got crawfish; it was also very yummy. The price is up there but it's *fair* considering that we are in the Midwest and this the first (primarily) shellfish restaurant there is in Madison. You can taste that the shellfish isn't "we bought this today from the docks" fresh but it's by no means not worth a visit. Worth the trip, food is amazing, seasoning works well.
Only problem I had was that the service was relatively slow; however it just opened so I'm sure they'll get better with time to come. One thing that I noticed is that there seemed to be no bussers, that would probably help the wait staff attend more responsively and just have someone focus on clearing the tables, since it is quite a mess when a group leaves.
