Located in Lake Geneva, Wisconsin, Joni's Diner is the premier breakfast stop in town.

Joni's Diner is not just a restaurant, we are an establishment that combines hospitality, a  memorable atmosphere and good eats made with local and fresh ingredients. Built in 1954, this L-Shaped Jerry O'Mahoney made its debut as the Decoven Diner in Duncannon, Pennsylvania until 2005. It has since then been moved to Fairfield, Connecticut in hopes of success and was eventually bought and shipped to it's current home in Lake Geneva. Our goal is to maintain the old time atmosphere while integrating quality food and great service for our customers.
