Never was the old adage "Don't judge a book by its cover" so true as when it comes to some of the best, most delicious restaurants in all of Wisconsin. If you're looking for fancy decor and white tablecloths, these joints aren't for you. But if you're looking for stellar food without the fuss, start making a list and plan to visit these unsuspecting restaurants in Wisconsin.

1. Mickey Lu's - Marinette

Mickey Lu's feels like a blast from the past - a greasy spoon type place that looks like it's from a 1950's sitcom. The burgers are made over an open flame and you get to watch your meal being made. Located at 1710 Marinette Ave, Marinette, WI 54143. For more information, visit the Facebook page for Mickey Lu BBQ in Marinette.

2. Steve's Pizza Palace - Platteville

Whenever I make a list like this, the comments are full of people telling me I should have added Steve's. The exterior looks like an Irish pub, but inside you'll find some of the best pizza anywhere in the state.

Located at 175 W Main St, Platteville, WI 53818. For more information, visit the website for Steve's Pizza Palace in Platteville.

3. Broadway Diner - Baraboo

With an outside that looks straight out of a Route 66 postcard and a menu chock full of filling, wonderful meals, this is a spot that can't be beat. Located at 304 Broadway St, Baraboo, WI 53913. Visit the website for Broadway Diner to learn more.

4. Cozzy Corner - Appleton

You might drive by this spot a time or two before you even spot it, but those in the know have taken note and could drive here with their eyes closed. Soul food in central Wisconsin isn't a combination you'd think would go well, but Cozzy Corner proves us wrong. The food here is full of love and flavor and it's a total gem you have to find for yourself. Located at 111 N Walnut St, Appleton, WI 54911.

Tucked into the basement of an office building in Milwaukee's downtown, these guys are a special lunch spot for those smart enough to seek it out. You'll love the huge plate of amazing flavors. Located at 770 N Jefferson St, Milwaukee, WI 53202. To learn more, visit Shah Jee's Facebook page.
