Yes & No, to clarify – Guests can use their cell phones to an extent.
We do not allow guests to be in an active phone or video call while in the store for security purposes – we cannot verify the age of the person on the other line and do not want to be selling to a patron that will provide the products to minors.
We do understand though, that guests may be looking at our online menu or passing time while waiting to be served and that is not an issue.
