Pizzeria. You have two primary choices when entering starting a pizzeria. One is a to-go restaurant in a modest facility with a specialized menu highlighted by pizza and beer, limited seating and a self-service atmosphere. The other is a full-service pizza restaurant with a menu that features not only a variety of pizzas, beer and wine, but also Italian entrees like spaghetti, ravioli and lasagna, side dishes such as salads (or even a salad bar), and a few desserts. The foundation of a pizzeria is, of course, the pizza. If you don't know how to make a good pizza, hire a good pizza cook who does. Invest in top-quality ingredients and preparation methods, and make every pizza as if you're going to eat it yourself. Do that, and your customers will keep coming back for more.
