The session restaurant is the restaurant you are currently logged into. With the enterprise module, you are allowed to make changes that affect other locations beyond the session restaurant. There are areas of Toast Web that are designed to work only with the session restaurant and other areas that are designed to work with multiple locations in the context of the enterprise module. As you read through this section, you will learn which areas of Toast Web you should use (and which you should avoid) when working with multiple locations. In particular, make sure you use the Advanced properties page to edit your menus for multiple locations and use the Publish config page to publish your changes to your restaurants. See Advanced properties and price editor pages and Publishing changes for multiple locations for more details.
Also, any permissions you specify for your employees apply to the session restaurant only unless you explicitly provide them access to other locations.
