Threat of substitute product or service: If the market is thronged with a different variety of the same product or activity, it becomes habitual on behalf of the customer to look out for the best of the lot (Crane, 2010). If Ninja New York is faced with the threat of a new Japanese fine dining facility around the corner, it should pay extra heed to its service rendition. Food quality, service quality, ambience, cost differences would matter a lot in determining as to how much people would opt for Ninja New York instead of any other Japanese restaurant. The former’s greatest plus point would be its innovation in the wholesome presentation and appearance of the restaurant, which is entertainment along with superbly excellent cuisine.
替代产品或服务的威胁：如果市场挤满了相同的产品或活动的不同品种，它变得习惯代表客户寻找最好的地段（起重机，2010）。如果忍者纽约面临的一个新的日本餐饮设施附近的威胁，它应该特别注意其移交的服务。食品质量，服务质量，环境，成本差异有很大关系确定为多少人会选择纽约而不是其他忍者的日本餐厅。前者的最大加点会在餐厅的卫生和表现形式的创新，它是随着高档美食娱乐。
