St Donatus! Being originally from Dubuque, one of the only things that keeps me coming home for weddings is knowing that just about every wedding reception will be catered by Kalmes.
Ha, I didn't know it was that popular. My in-laws live in Ankeny but they are all from Dubuque and they used to have a huge family (like entire family) farmhouse out near that place so I've been there a couple times. Very good stuff.
Also, what is the other place in Dubuque that is really old but it burnt down a few years ago? If I am not mistaken, they rebuilt it and it burnt down again! Sad stuff. We went there for Thanksgiving one year.
