The Lunch Encounter 
FYI, it is in the process of moving to Middleton. I drove by when I was in Madison over Labor Day and it looks like they are moving into a great space.
Thanks, Ellen! I need to update the listing.
If you ever have a chance to chat with Barry Levenson, Mayor of Mustardville, do so, he is the best.
Funny and friendly, Barry knows mustard, marketing, humor, baseball, even the law (REFORMED lawyer, Assistant Attorney General, State of Wisconsin). He writes comedic satirical operettas, non-fiction tomes, silly slogans, you name it.
A peach, no pit.
Thanks for the lovely comment and thanks for reading! Midnight Snack
