Church Brew Works, or Church Brewery, is a brewery and restaurant located in a restored former St. John the Baptist Church, a Roman Catholic church.  The church was built in 1902 and was in use as a church until 1993.  Church Brewery opened in the former church in 1996 and it has become a classic ever since.  You can find more information here:
