Generally yes shakes are gluten free IF its a real dairy shake (many are not). Even though a food may contain primarily gluten free ingredients, there is a strong potential for cross contamination. For example, if a restaurant is making your milk shake in the same area that they prepare bread, there is a risk of exposure.
If the shakes are handspun the shake mixer may also have mixed cookies & cream shakes. So, unless you are there when they are not busy & can get an employee to clean the machine, you may want to stay away from the shake.
In addition the Culver's here at my home on the west coast of Florida you can request a Udi's gluten free bun.
