For our stage shows food isn't included, the events are held in venues similar to where you might watch a stand-up comedy show, a play or a music concert. A bar will almost certainly be open for drinks but you will need to check directly with the venue for any food options they might offer. 

NB: If you are attending a Gala Dinner yes, of course, and this will be stated on the page where you ordered your tickets. Drinks will be available to purchase, any inclusive drinks will be specified on the ticket page.
