If you partner with someone else to make a restaurant, if you don't have the catering backstage technology and the other party does, will it be more risky?
That depends on your relationship. If you two have been friends for many years, have deep feelings and are true friends, there will be no problems you mentioned, but you can save a sum of money. If it's just a partner, it's better to distinguish clearly. Partners just think more about their own interests. It is not good to avoid conflicts in the future.
