This is a new restaurant that opened up near Esplanade and shares their space with Biermarkt. I went with a group of 8 people on a weekday and it wasn't too busy. Overall, I enjoyed their beer and specialities. The food could have been better, but it's a brewery so you don't expect much anyways.
They give you two menus, one from Biermarkt and the other that list their own Goose Island specialties. I ordered the January/February speciality, (I believe it's called the silver smith lager) and the chicken carbonara. The beer was really sweet. The chicken carbonara was a bit bland and the noodles are potato shavings.
I also tried their Goose Island speciality (ale) and fruit beer in the Biermarkt section and really liked it.
I would come back here with friends for a drink, but not for food.
