No...but your income is different. If you own the business, but do not actually participate in the day-to-day operations, you're considered an 'investor' ... if you work, you should get 'paid' for your 'work' (@ market pay rate) then take 'profits' as an investor. Of course, it depends on how you set-up your restaurant (i.e. Sole Proprietor, Incorporate, LLC, etc.). If you're only the 'owner' you're really an 'investor' if you don't 'work'. Your income may be taxed differently depending on your set-up (incorporated, LLC, Sole Proprietor, etc). You should seek help from tax advisor or CPA.
If it is successful and you can afford to hire people to look after it, then you don't have to work there. A friend of mine owns a restaurant. After 6 years it is now successful enough that he can afford to hire someone to run it.
