The Jordandal Cookhouse is a small takeout storefront recently opened by Jordandal Farms, known in the Madison Area for quality meats. The menu has a variety of sandwich-centered options centered around those meats with some additional items available during dinner.
We ordered the Bahn Mi and the Ginger-Soy chicken. Both were very good. The Bahn Mi had sausage, ham and pork pate on a delicious, crispy french roll. The chicken came with rice noodles and lettuce for wrapping. And both came with a choice of a side - we got sweet potatoes w/ bacon & a corn-based salad.
Located in a small strip mall about a mile from Epic's Campus (which, I'll assume is the reason you are searching Yelp for food in Verona, WI), the interior is small, with just enough room for a takeout counter, a fridge and freezer. There were a few chairs and a table outside.
If you're staying in Verona for Epic-related business, and aren't looking to venture into Madison for food, Jordandal Cookhouse would be my first (and only) recommendation.
