The menu is pretty extensive with a range of pizzas which should meet everybody's tastes. We ordered a tourist menu (18 soles) and a "personal" pizza pizza (15). The tourist menu is the standard deal - soup or salad, main courses (includes pizza), a choice of side, desert and a drink. The pizza had a good amount of topping and was more than enough for one.
Service was fine, although we were the only ones in the restaurant.
