r/spaghetti

Hi. I and my husband own a small hotel and we have a small restaurant attached to it. We only make hurgers, fries, wings (we currently microwave frozen ones) , onion rings for now but my husband always compain that I should make some other stuff too. he always says we need to make some real food. I was thinking about steaks but im scared to make them because people might complain if it is no properly cooked especially if it is medium rare or medium. So I'm thinking about spaghetti since I'm good at making spaghetti and my kid likes the spaghetti that I make. But are the restaurant ones much harder to make than home made ones? Of course we will buy more expensive noodles and sause. but all we do at home is boiiling it and pouring the sause on it. but are there any other secret method for restaurant ones?
