Venues are event locations (your own rooms or partner spaces) that customers can book as part of a catering order, with their own availability times. The Order: Venues tab holds three settings: Venues: Title (default Venues - the label used for the venue line in the cart and order summaries), Catering: Show Venues on Proposals and Catering: Ordering On Venues. Venues themselves are created under the Venues page in the admin menu, and the master Allow Venues switch lives on the Business: General tab.
