My husband and I visited Steak'n Shake last week for the first time in years and I was not disappointed. First of all I forgot how cheap it is! We both got the Wisconsin Mushroom Swiss burger with fries ($4). You can now also get regular fries or add Cajan or Parmesan flavoring to them. I got the cajan fries and they were pretty good- but I think I'll stick with the regular next time as it was essentially a cajan salt seasoning they sprinkled on the fries- not tossed or cooked with.
As far as the burger goes it was awesome! It was cooked perfectly and the bun was soft, yet slightly crispy. I didn't get a milkshake because I didn't have the healthiest lunch, but they have a variety of flavors- including seasonal ones like pumpkin and egg nog so be sure to ask if they have a seasonal one next time you go.
Lastly, our server was nice and attentive. He made sure our waters were filled and took care of us.
Next time I'm in the area I'll consider Steak'n Shake again for a guilty, greasy lunch.
