I finally went to the Sons of Norway Lutefisk & Meatball dinner and had a blast (and actually liked the lutefisk). Now I'm seeking out other events that might give me a chance to try some new dishes. Here's what I've found through December. If anyone has been to one of these and can provide input or add any other events, that would be great!
