Keto Restaurant Guide
Keto at Culver's
Culver's is known for ButterBurgers, cheese curds, and frozen custard, and only the first one works on keto. The lightly toasted buttered bun carries almost all of a burger's carbs. In Culver's official nutrition guide, removing the bun takes a ButterBurger Cheese Double from 40g of carbs to 2g, and a Culver's Deluxe Double from 42g to 4g.
Sides are where it gets tricky. Cheese curds sound keto but are breaded and fried, at 46g of carbs for a medium. Steamed broccoli and the garden side salad are the low-carb sides, and buttermilk ranch is the lowest-carb dressing at 2g. Every custard item, from a single scoop to a Concrete Mixer, is high in sugar.
