I’ve installed the hospitality app on ERPNext. And enabled the modules and roles for that app. But I still do not see any options to add restaurants or hotels. Neither in the sidebar or in the search
If not enabled then please go to the Domain Settings and Enabled the module.
In Version 14, I think hospitality doesn’t have workspace so …
And also check it.
I think the service is disabled.
Thank You!
Yes, there’s been no active development on that module.
I still don’t see “Hospitality” in Domain setting
Out of support, the module does not work properly in v14. If it worked, then you have to solve the issues yourself, one by one. 
Lots of issues there, like path issues, and domain issues.
