I'll be brief, because Tornado Room's late night menu is a legend throughout Madison.
The steak sandwich is great, especially for the price. My dining partner and I each ordered a steak sandwich, and split an order of steak fries.
The service is phenomenal. Very genuine and friendly staff. One of my favorite parts of the meal is filling out a postcard from the restaurant which they will send out on your behalf (free of charge!) a really fun touch. :)
Pro tip: The perfect cocktail to accompany this dining experience is a dirty martini.
