Thanks to Nathan for emailing to let us know that Steak n’ Shake has a great allergen menu:
This midwestern establishment has taken root throughout the country. It is a causal burger and fry chain that is known for Steakburgers and hand-dipped milkshakes.Okay, you might want to skip the milkshakes, but the allergen menu can help you find some suitable options (it’s accessible via the Menu pages). Following the allergen menu, you will find a full list of ingredients for all of the burger components.
The allergen menu at Steak ‘n Shake is full of surprises, too! While some buns contain milk, others do not (at last check the shooter buns and knotted buns were dairy-free). And though the cheesy fries are obviously off limits, several of their seasoned French fry varieties are made without dairy. We also found it incredible that most of their flavorful sauces are also dairy-free.
See their website below for locations, phone numbers, and to view the full menu.
